β¦ Synopsis
The analysis of the intensity excess function for the infrared C-D Stretching band of deuterated chloroform in mixtures with acetone, acetophenone and benzophenone as well as the analysis of the position of the PMR chloroform signal in the above mentioned mixtures are the basis for elucidation of the structure of complexes formed between chloroform and ketones.
