Far-infrared spectra of HCI in dense Ar: analysis of two time correction functions for the interaction

The pure rotational spectrum of a small diatomic molecule inmersed in a medium is analyzed using two different stochastic bath description: an Ornstein-Uhlenbeck (Gaussian bath) process with a time decay exponential correlation and a δ (drastic Markovian bath) process.

Description
Summary:The pure rotational spectrum of a small diatomic molecule inmersed in a medium is analyzed using two different stochastic bath description: an Ornstein-Uhlenbeck (Gaussian bath) process with a time decay exponential correlation and a δ (drastic Markovian bath) process. Aplication to HCl in dense gas Ar shows that at low (high) densities the spectrum is well described in terms of the drastic Marckovian (Gaussian) bath.
