Highly excited vibrational states of HCN around 30 000 cm-1.
This article describes the analysis and interpretation of rovibrational spectra involving highly excited vibrational states in the molecule of HCN. The spectra were obtained by means of the vibrationally mediated photodissociation technique. Analysis of the spectra revealed four bands with Sigma-Sigma structures that, once fitted, provided the energies and rotational constants of four new, high...
متن کاملSpectroscopy of highly excited vibrational states of HCN in its ground electronic state.
An experimental technique based on a scheme of vibrationally mediated photodissociation has been developed and applied to the spectroscopic study of highly excited vibrational states in HCN, with energies between 29,000 and 30,000 cm(-1). The technique consists of four sequential steps: in the first one, a high power laser is used to vibrationally excite the sample to an intermediate state, typ...
متن کاملHighly Excited Vibrational States of the KCN Molecule
Vibrational (J = 0) states for the KCN molecule are calculated in Jacobi coordinates, employing a discrete variable representation (DVR) for the angular internal coordinate. The power of the DVR method is once again illustrated in that some 800 vibrational (J = 0) states are converged for a two-dimensional potential-energy surface. The energy region studied is that where the classical dynamics ...
متن کاملVibrational relaxation of highly excited toluene
The collisional loss of vibrational energy from gas-phase toluene, pumped by a pulsed KrF laser operating at 248 nm, has been observed by monitoring the time-resolved infrared fluorescence from the C-H stretch modes near 3.3 p,m. The fragmentation quantum yield of toluene pumped at 248 nm was determined experimentally to be -6%. Energy transfer data were obtained for 20 collider gases, includin...
متن کاملThe Study of Dynamical Potentials of Highly Excited Vibrational States of HOBr
The vibrational nonlinear dynamics of HOBr in the bending and O-Br stretching coordinates with anharmonicity and Fermi 2:1 coupling are studied with dynamical potentials in this article. The result shows that the H-O stretching vibration mode has significantly different effects on the coupling between the O-Br stretching mode and the H-O-Br bending mode under different Polyad numbers. The dynam...
