On the interaction between the radiation field and ionic crystals
@article{Huang1951OnTI, title={On the interaction between the radiation field and ionic crystals}, author={Kun Huang}, journal={Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences}, year={1951}, volume={208}, pages={352 - 365} }
A symmetric treatment of the interaction between the radiation field and a diatomic ionic crystal with optical isotropy is presented; the explicit solutions of the problem can be readily obtained, which describe all the possible modes of vibration of the combined system of the radiation field and the ionic lattice. An unexpected conclusion is that the optical waves immediately below the infra-red dispersion frequency are in fact none other than what are normally considered as the transverse…
