Abstract
The absorption intensities of the CH and CD stretching vibrations of some deuterated benzene monoderivatives have been measured in CCl4 solution. The compounds are of the type 4-D-phenyl-X and 2,4,6-D3-phenyl-X. The observed intensities can be interpreted as sum of contributions Io, Im, and Ip, of the participating CH or CD oscillators. By using also the data for the undeuterated compounds phenyl-X these bond contributions can be evaluated separately. They show a decrease with the Taft substituent parameter σI, that is greatest in ortho and smallest in para position. The isotope intensity sum rule is verified for the CH and CD stretching vibrations in all the cases considered.
