Abstract

We consider the effective field theory based on the consideration of the rotation and libration of molecules in surroundings represented as effective clusters. The suitable distribution function with respect to the number of particles, which form a cluster, is discussed. This approach is applied to the forecasting of infrared spectrum frequencies of liquids using liquefied inert gases, nitrogen, oxygen, benzene and water as examples.
