Predictions of Infrared Intensities by Transferring Atomic Polar Tensors

Predictions of Infrared Intensities by Transferring Atomic Polar Tensors 

Atomic polar tensors derived from measured integrated infrared intensities may be used to predict intensities in other molecules containing the same atoms in a similar envirorunent. A comprehensive review on the subject has been published by Person [128], By using Eq. (4.16) and Px matrix constructed from transferred atomic polar tensors, the matrix of dipole moment derivatives with respect to normal coordinates in the new molecule is obtained 

Some of the difficulties encountered may be avoided by transferring vibrationa] polar tensors only, while calculating the rotational part for the particular molecule considered if the dipole moment is known. These options appear not to have been pursued.
