"The mass drop percentages from the start of the test until reaching the T onset value were ∼5.0% for the CAM–LnA system and ∼3.0% in the cases of CIT–LnA and PIP–LnA systems."

"For example, the CAM–LnA system shows two prominent peaks around 1750 cm –1 , which correspond to characteristic stretching vibrations from both CAM and LnA, albeit with shifts in intensity due to the change in concentration."
