Conformational characteristics of methyl nitrite: a cryospectroscopic study

Mid-infrared spectra of methyl nitrite that exist as a mixture of cis and trans conformers in the solutions of liquid argon, krypton, and xenon are examined as a function of time at different temperatures. The methodology used to make kinetics measurements of thermodynamic parameters, such as enthalpy, entropy and free energies of the conformer equilibrium in the vapor phase and in several solvents are discussed.
