CALM1 binds B3LYP. 25 / 25

"The success of CAM-B3LYP (and other range-separated functionals) is due to the fact that it includes a long-range correction of the exchange potential, which incorporates an increasing fraction of Hartree–Fock (HF) exchange as the interelectronic separation increases."

"Other possible choices include the range-separated hybrids, i.e. ωB97X-D and CAM-B3LYP functionals or the dispersion-corrected B3LYP which also performs quite well."

"For Fe–Fe/Mo–Fe distances, CAM-B3LYP gives worse deviations for both spin-coupled (and diamagnetic complexes) than its parent B3LYP functional with MD = +0.061 Å (MAD 0.067 Å) and the recent ωB97M-D3BJ functional (found to be highly accurate for main group thermochemistry) xref , xref offers no improvement either, with MD of +0.067 Å (MAD = 0.067 Å)."

sparser
"Aside from LC being applied to LDA or GGA functionals, xref exemplifies other specific adaptations of the range-separation idea, incorporated in the design of the functional, such as in CAM-B3LYP, M11 [ xref ] and HSEH1PBE [ xref ] cases."

"Among the plethora of functionals, the most often used to simulate the spectra of porphyrins are: B3LYP, CAM-B3LYP, and PBE0 [ xref , xref , xref , xref , xref , xref ]."

"xref shows that B3LYP, BHandHLYP, LC–wPBE, CAMB3LYP, wB97XD, and HF calculations give positive values for the complexation energy of the H 2 @C 50 complex, suggesting that this complex is thermodynamically unstable, regardless of the basis set used, 6-31G(d,p) or 6-311G(d,p)."

"In contrast, the CAM-B3LYP method exhibited slight overestimates on the excitation energies of T-705/BC23, T-705/B 12 N 12, and T-705/CB 11 N 12 complexes and underestimates at T-705/C 24 as compared to the UB3LYP method in gas and aqueous phases, xref , xref ."

"Looking at just the number of matched peaks, the functionals B3LYP, PBE0, PBE0-D3, CAM-B3LYP, CAM-B3LYP-D3 and ωB97X-D are on par with each other, having identified 138, 140, 139, 139, 137, 139 peaks, respectively, which means it is fair to compare their MAEs."

"The rate-determining step can be either the bond rotation or the proton transfer, depending on the rotating bond and the meso -substituents. xref , xref For this particular switch, several density functionals were benchmarked against CCSD(T)/6-31G data, concluding that both CAM-B3LYP and M05-2X provide the most reliable results. xref Besides the Hückel–Möbius interconversion, we also considered the switching from 28M to 28F with the associated transition state ( 28TS 3 ), as shown in."

sparser
"The CAM-B3LYP function was used in collaboration with the 6-311+G(d,p) basis set and the time-dependent density functional theory to do the theoretical UV–Vis assessment (TD-DFT)."

sparser
"The worst performer in that range is still the M06L functional, however the best turns out to be the dispersion-corrected CAM-B3LYP."

sparser
"It was shown that all excitation wavelengths were lowered when CAM-B3LYP was used (in contrast to B3LYP results)."

"Contrary to CAM-B3LYP, the long-range exact exchange in PBE0r is screened away, in the spirit of the Random-Phase approximation."

"Partial conclusions from the above discussion suggest the Grimme-type alleviation as closer to the physical realism, curing drawbacks appearing in the pure B3LYP and incompletely resolved in CAM-B3LYP."

sparser
"The range-separated hybrid functionals, i.e., CAM-B3LYP, ωB97M-D3BJ, and ωB97X-D3BJ, appear not to offer clear advantages over the regular hybrid functionals."

sparser
"The time-dependent density functional theory (TD-DFT) calculations were investigated with the CAM-B3LYP functional [ xref ] since it gives rise to more reliable results compared to pure B3LYP on the nature of electronic transitions spectra to get further insights into the electronic absorption of T-705–nanocage complexes in the gas and aqueous phases."

sparser
"CAM-B3LYP strongly disfavors Baird aromaticity, yet based on this feature, one may also single out which macrocycles with high certainty are Baird-aromatic in reality."

sparser
"Range-separated hybrid functionals show significantly poorer performance compared to the meta -GGA hybrids, except for CAM-B3LYP-D3 (RMSD = 1.8 kcal mol –1 ), as pointed out in previous benchmark studies on expanded porphyrins. xref , xref We recently proved that M06-2X and CAM-B3LYP exhibit very similar degrees of π-electron delocalization in expanded porphyrins. xref Disappointingly, the promising range-separated hybrid ωB97M-V with nonlocal correlation, xref designed using a combinatorial approach and containing only 12 parameters, clearly underperforms the older ωB97XD for topology interconversions in expanded porphyrins."

"Based on numerous reports, it is usually advised to use CAM-B3LYP to predict adsorption spectra [ xref ]; see xref ."

"In the singlet excited states Kim, Nakano, Yamago, and co-workers recently revealed rapid interconversion between self-trapped exciton and delocalized states, xref yet it has earlier been found through time-dependent CAM-B3LYP calculations that the S 1 state of [ n ]CPP ’s is more delocalized than the T 1 state. xref Similar observations in the T 1 state of various [ n ]CPP ’s could give experimental support as to which functional gives the right description: UB3LYP or UCAM-B3LYP?"

"They demonstrated that the overestimation by 0.5 eV (in respect to the experimental data) of the transition energy for the relevant TPA state in [5,15-bis(3,5-bitert-butylphenyl)-10,20-bis(trihexylsilylethynyl)porphyrinato]zinc by B3LYP led to a 5-fold overprediction of the TPA cross-section for this molecule, whereas for 5,5′-(ethyne)bis[[10,20-bis(3,5-bitert- butylphenyl)-porphyrinato]zinc], underestimation of the transition energy by 0.5 eV with CAM-B3LYP and by 0.8 eV with B3LYP lead to underestimations of the TPA cross-section by factors of 2 and 4, respectively [ xref ]."

"Just as in the case of B3LYP, the original CAM-B3LYP functional closely reproduces the coupled cluster reference values."

"CAM-B3LYP cross-section values were much smaller than those determined with B3LYP."

"This observation is also validated by examining R 2 values (0.9931 for TD-B3LYP, 0.9906 for TD-M06-2X, 0.9909 for PBEPBE, 0.9915 for BMK, 0.9936 for wB97XD, 0.9935 for CAM-B3LYP, and 0.9928 for CIS) calculated for correlation of the calculated excited-state frequencies with those of the experiment."
