    "abstract": "Without invoking the Markov approximation, we derive formulas for vibrational\nenergy relaxation (VER) and dephasing for an anharmonic system oscillator using\na time-dependent perturbation theory. The system-bath Hamiltonian contains more\nthan the third order coupling terms since we take a normal mode picture as a\nzeroth order approximation. When we invoke the Markov approximation, our theory\nreduces to the Maradudin-Fein formula which is used to describe VER properties\nof glass and proteins. When the system anharmonicity and the renormalization\neffect due to the environment vanishes, our formulas reduce to those derived by\nMikami and Okazaki invoking the path-integral influence functional method [J.\nChem. Phys. 121 (2004) 10052]. We apply our formulas to VER of the amide I mode\nof a small amino-acide like molecule, N-methylacetamide, in heavy water.",
