For non-polar molecules like $N_{2}$ and $CO_{2}$ the origin of the intensities lies in the non-zero dipole derivatives where the dipole is induced by the molecular quadurupole moments of the neighboring molecules in the lattice. The distortion moment is neglected. The results of the theory have been applied to experimental information, as far as available, for $N_{2}, CO_{2}$, and CO. Agreement between theory and experiment is found to be very good to within the error of the experimental data, i.e. a factor of 2. The theory also accounts satisfactorily for failure to observe absorption in solid $O_{2}$ and $CH_{4}$ for sample thicknesses investigated to date. en_US dc.format.extent 119699 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title THEORY FOR THE INFRARED ABSORPTION INTENSITIES OF THE LATTICE VIBRATIONS OF MOLECULAR SOLIDS. en_US dc.type article en_US
