Characteristic vibrational frequency
The vibrational temperature is commonly used in thermodynamics, to simplify certain equations. It has units of temperature and is defined as where is Boltzmann's constant, is the speed of light, and (Greek letter nu) is the characteristic frequency of the oscillator. The vibrational temperature is used commonly when finding the vibrational partition function. WebPoor results Bad predicted vibrational frequencies based on comparing HF and MP2 calculations.

WebVibrational frequencies (and wavenumbers) increase in the order: single < double < triple, Vibrational frequencies (and wavenumbers) for bonds involving the lightest element, H, are high and In general, it is harder to stretch than to bend so stretching vibrations tend to occur at higher frequencies (and wavenumbers) than bends. WebVibrational Spectroscopy A molecule composed of n-atoms has 3n degrees of freedom, six of which are translations and rotations of the molecule itself. This leaves 3n-6 degrees of vibrational freedom (3n-5 if the molecule is linear). Vibrational modes are often given descriptive names, such as stretching, bending, scissoring, rocking and twisting.
