Infrared intensities in condensed phases
INTRODUCTION In this paper we wish to bring together, not a total review of all the work which has been done on liquid-phase infrared intensities, but rather a review of the development of our own studies and interpretations in this area. We choose this approach partly because reasonably recent overall reviews of the quite large amount of work done on liquid-phase infrared intensities can be found elsewhere' and chiefly because the present position with regard to such studies, as we see it, can be set forth most economically if we confine ourselves to the work of our own laboratory. Our interest, like that of other workers, arose from previous work on gas-phase intensities2 and the interesting molecular information deducible from such measurements. In the gas-phase, one can measure the Beer— Lambert law parameter a: ln(Io/I) = al (1)
