many bonds, and their vibrational spectra are correspondingly more complex, i.e. big molecules have many peaks in their IR spectra.[citation needed] The...

are observed in vibration–rotation spectra. The excited-state wave function is the product of two wave functions such as vibrational and rotational. The...

Simultaneous excitation of a vibration and rotations gives rise to vibration–rotation spectra. For a molecule with N atoms, the positions of all N nuclei depend...

rotational energy levels was developed to account for observations of vibration-rotation spectra of gases in infrared spectroscopy, which was used before microwave...

Rotational–vibrational spectroscopy is a branch of molecular spectroscopy that is concerned with infrared and Raman spectra of molecules in the gas phase...

differing reduced mass for the affected bonds. Isotope shifts in atomic spectra are minute differences between the electronic energy levels of isotopes...

according to [O3CrO–H]− ⇌ [CrO4]2− + H+ with a pKa of about 5.9. The infrared spectra of compounds containing the OH functional group have strong absorption...

energies for molecules. In terms of shape and size, rotational spectra and vibrational spectra allow for the determination of molecular moments of inertia...

molecule because there are more changes in vibrational energy level. For absorption spectra, the vibrational coarse structure for a given electronic transition...

interactions are also often associated with changes in the lengths and vibrational stretching frequencies of the covalent bond that gives rise to the sigma...

study of line spectra and most spectroscopy still does. Vibrational spectroscopy is the branch of spectroscopy that studies the spectra. However, the...

character tables were compiled by László Tisza (1933), in connection to vibrational spectra. Robert Mulliken was the first to publish character tables in English...

frequencies of hot bands in vibrational spectra. Because anharmonicity decreases the spacing between adjacent vibrational levels, hot bands exhibit red...

differences between the values for two metals. Other measures include the M–O vibration frequency and the M–O bond length. The strength of the M-O bond tends...

fingerprint to identify molecules. For instance, Raman and IR spectra were used to determine the vibrational frequencies of SiO, Si2O2, and Si3O3 on the basis of...

the corresponding effects seen in the vibrational circular dichroism (VCD) and Raman optical activity spectra (ROA) have been recently documented by...
