Abstract
Infrared measurements of the frequency and intensity of the C — D stretching and bending motions of CDCl3 in various solvents are presented. The expected relationship between heat of solution and lowered stretching frequency is shown not to extend to CDCl3. There is, however, a correlation between apparent integrated intensity of this band and the extent of interaction in the same solvent. The band is over thirty times as intense in triethylamine as in carbon tetrachloride solution. No large change in the intensity of the bending motion was observed. The infrared spectral properties of chloroform‐d are interpreted to indicate molecular interactions similar to hydrogen bondinginteractions.
