Vibrational energy relaxation of the cyanide ion in aqueous solution
TLDR
In this article, the authors reported the vibration energy relaxation (T1) of the CN− ion in saturated H2O/D2O and dilute H 2O solutions at room temperature.Abstract:
Vibrational energy relaxation (T1) of the CN− ion is reported for NaCN in saturated H2O/D2O and dilute H2O solutions at room temperature. Time domain measurements of the v = 1, 2080 cm−1 vibration shown T1 is on the order of a few picoseconds. The relaxation time increases with dilution and is apparently sensitive to cation (Na+,K+) and local solution structure.read more

TL;DR: In this article, a model based on semiclassical collision theory is presented to describe the dephasing of vibrationally excited molecules in a liquid, and it is shown that fluctuations of the vibrational frequencies which are caused by the intermolecular interaction, lead to phase relaxation of a coherently excited state.
