Energy-dependent collisional deactivation of vibrationally excited azulene

Collisional energy transfer parameters for highly vibrationally excited azulene have been deduced from new infrared fluorescence (lRF) emission lifetime data with an improved calibration relating IRF intensity to vibrational energy [J. Shi, D. Bernfeld, and J. R. Barker, J. Chern. Phys. 88, 6211 (1988), preceding paper]. In addition, data from previous experiments [M. J. Rossi, J. R. Pladziewic...

Temperature Dependence of Collisional Deactivation of Highly Vibrationally Excited Biphenylene

Collisional energy transfer between highly vibrationally excited biphenylene and a variety of monoand polyatomic bath gases has been measured at temperatures between 333 and 523 K. Biphenylene molecules were initially prepared with an additional vibrational energy of 28 490 cm by electronic absorption at 351 nm followed by fast internal conversion. The collisional deactivation was observed by d...

Dipole moments of highly vibrationally excited water.

The intensity of water absorption in the region of the solar spectrum plays a dominant role in atmospheric energy balance and hence strongly influences climate. Significant controversy exists over how to model this absorption accurately. We report dipole moment measurements of highly vibrationally excited water, which provide stringent tests of intensities determined by other means. Our measure...

Collisional energy transfer in highly excited molecules.

The excitation/de-excitation step in the Lindemann mechanism is investigated in detail using model development and classical trajectory studies based on a realistic potential energy surface. The model, based on a soft-sphere/line-of-centers approach and using elements of Landau-Teller theory and phase space theory, correctly predicts most aspects of the joint probability distribution P(ΔE,ΔJ) f...
