Abstract

The v' = 0-4 vibrational levels of the b4S- state of NO in Ar and Kr matrtixes were selectively excited in the near-IR by a tunable laser from the metastable a4P state previously populated by an ArF excimer laser. One of the decay channels of the b state is a radiationless transition to low vibrational levels of the B2P state. By monitoring the time- and energy-resolved B2P->X2P fluorescence the energies were detd. of the b, v' levels and the propensity rules of the b, v' -> B, v" transitions. The results are in good agreement with the previously proposed model assuming an important role for the b4.sum.- state in the radiationless relaxation from the A2S+ (Rydberg) to the final radiative valence states B2P and a4P.

Molecular vibration

A molecular vibration is a periodic motion of the atoms of a molecule relative to each other, such that the center of mass of the molecule remains unchanged. The typical vibrational frequencies range from less than 1013 Hz to approximately 1014 Hz, corresponding to wavenumbers of approximately 300 to 3000 cm−1 and wavelengths of approximately 30 to 3 μm. For a diatomic molecule A−B, the vibrational frequency in s−1 is given by , where k is the force constant in dyne/cm or erg/cm2 and μ is the reduced mass given by .

Laser

A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word laser is an anacronym that originated as an acronym for light amplification by stimulated emission of radiation. The first laser was built in 1960 by Theodore Maiman at Hughes Research Laboratories, based on theoretical work by Charles H. Townes and Arthur Leonard Schawlow. A laser differs from other sources of light in that it emits light that is coherent.

Rotational–vibrational spectroscopy

Rotational–vibrational spectroscopy is a branch of molecular spectroscopy concerned with infrared and Raman spectra of molecules in the gas phase. Transitions involving changes in both vibrational and rotational states can be abbreviated as rovibrational (or ro-vibrational) transitions. When such transitions emit or absorb photons (electromagnetic radiation), the frequency is proportional to the difference in energy levels and can be detected by certain kinds of spectroscopy.
