Abstract
Variable-temperature infrared (IR) spectra of cyclohexane and IR and R aman spectra of chlorocyclohexane have been investigated by graphic ei genvalue analysis. Thermal effects known as peak shift and band broade ning combined with heteroscedastic noise in vibrational bands are foun d to have severe influence on the interpretation of the outcome of ran k analysis. Methods for correction of frequency shifts and band broade ning in the spectral profiles due to temperature variation are develop ed and tested.
