Abstract
IT has recently been suggested1,2 that the attenuated total reflectance (ATR) technique is superior to the conventional transmission technique for obtaining the infra-red spectra of aqueous solutions, with the implication that the intense absorption bands of liquid water appear to be relatively weaker in ATR spectra. We have examined the spectra of a number of aqueous solutions by both methods and have in no case found the ATR, spectra to be superior.
