Two-dimensional Infrared Spectroscopy
... spectroscopy technique that has the ability to correlate vibrational modes in condensed-phase systems ... This technique provides information beyond linear infrared spectra, by spreading the vibrational information along multiple axes, yielding a frequency correlation spectrum ... correlation spectrum can offer structural information such as vibrational mode coupling, anharmonicities, along with chemical dynamics such as energy transfer rates and molecular dynamics with femtosecond time ...
Franck–Condon Principle
... Vibronic transitions are the simultaneous changes in electronic and vibrational energy levels of a molecule due to the absorption or emission of a photon of ... electronic transition, a change from one vibrational energy level to another will be more likely to happen if the two vibrational wave functions overlap more ...
Rotational-vibrational Spectroscopy - Rotational-Vibrational Spectroscopy
... See also Rotational spectroscopy Generally vibrational transitions occur in conjunction with rotational transitions ... possible to observe both rotational and vibrational transitions in the vibrational spectrum ... Although many methods are available for observing vibrational spectra, the two most common methods are infrared spectroscopy and Raman spectroscopy ...
Vibrational Hot Bands
... approximation, the normal modes of a molecule are not coupled, and all vibrational quantum levels are equally spaced, so hot bands would not be distinguishable from so-called "fundamental ... of real molecules always have some anharmonicity, which causes coupling between different vibrational modes that in turn shifts the observed frequencies of hot bands in ... Because anharmonicity decreases the spacing between adjacent vibrational levels, hot bands exhibit red shifts (appear at lower frequencies) than the corresponding fundamental transitions ...
Hot Band
... In molecular vibrational spectroscopy, a hot band is a band centred on a hot transition, which is a transition between two excited vibrational states, i.e ... In infrared or Raman spectroscopy, hot bands refer to those transitions for a particular vibrational mode which arise from a state containing thermal ... modes with a single photon, and overtones, which are transitions that involve changing the vibrational quantum number for a normal mode by more than 1 ...
