  Within the framework of the Lindblad master equation, we propose a general
methodology to describe the effects of the environment on a system in dilute
gas phase. The phenomenological parameters characterizing the transitions
between rovibrational states of the system induced by collisions can be
extracted from experimental transition kinetic constants, relying on Energy Gap
fitting laws. As the availability of this kind of experimental data can be
limited, the present work relied on experimental line broadening coefficients,
however still using Energy Gap fitting laws. The 3 $\mu$m infrared spectral
range of acetylene was chosen to illustrate the proposed approach. The method
shows fair agreement with available experimental data while being
computationally inexpensive. The results are discussed in the context of state
laser quantum control.
