Theoretical descriptions of various 2D surface vibrational spectroscopies are presented. One can effectively use the methods to investigate the vibrational couplings of adsorbed molecules on surfaces and at interfaces since they are either three- or five-wave-mixing processes. One can extract quantitative information on the anharmonicity of the multidimensional potential energy surface as well as on the nonlinear coordinate dependencies of the dipole moment, polarizability, and first hyperpolarizability by using the novel 2D surface vibrational spectroscopies.
