Collision-Induced Light Scattering. Relation Between Spectral Shape and Molecular Interaction

분자충돌에 의한 광산란
Hyung Kyu Shin

분자 혹은 원자간의 충돌에 의한 light scattering의 강도를 계산하는 이론식을 유도하였다. Argon을 예로하여 적은 진동수 shift에 나타나는 좁은 분광 band는 원자간의 장거리 효과가 이방성에 미치는 영향에 의한 것이고 큰 진동수 shift에서의 넓은 분광 band는 단거리 효과에 의한 것임을 지적하였다.

An analytic expression for the intensity of collision-induced light scattering obstained by introducing both short-range and long-range effects on the induced anisotropy. By taking argon as a specific example, it is shown that a narrow band at small frequency shifts is caused by long-range effects, while a broad band in the far wing of the spectrum is due to short-range effects. The overall intensity is a synthesis of these two bands and does not follow a simple exponential form. As temperature increases, the intensity at large frequency shifts increases makedly, while at small frequency shifts it changes little.
