摘要
Mid-infrared spectroscopy (400–4000 cm−1) of Bisphenol “AF” is manifested. Bisphenol “AF” is another variant of Bisphenol “A,” besides Bisphenol “S.” Bisphenol “A” is being curbed due to its malign effects. Bisphenol “AF” is gradually taking the place of Bisphenol “A.” Bisphenol “AF” tends to have malignancy similar to Bisphenol “A.” Various molecular signatures of Bisphenol “AF” have been observed by mid-infrared spectroscopy, which include C-H and O-H stretching vibrations. Observed vibrations are analyzed by density functional theory calculations for possible countermeasure. Principal component analysis is used on detected absorption frequencies of Bisphenol “AF” in conjunction with prior reported frequencies of Bisphenol “A” and “S” in the mid-infrared range. As a result of principal component analysis, the list of correlating absorption frequencies of bisphenol “A,” “S,” and “AF” in the mid-infrared range is populated, showing the role of benzene rings. This correlation may lead to a group of toxic materials and to finding the origin of their toxicity by knowing the nature of correlated vibrations and the related involvement of functional groups and atoms.
