The vibrational, rotational, and vibrational-rotational spectra of dil. H2, D2, and HD matrix-isolated in solid Kr and Xe were calcd. at zero temp. and at pressures P = 0-570 kbar. The impurity local mode frequencies were calcd. vs. pressure. The pure vibr ...
Three new progressions consisting of broad bands were obsd. in the absorption spectrum of NO in solid Ar. They are identified as the mol. Rydberg A 2.sum.+,C 2P and D 2.sum.+-X 2P (v', 0) transitions, blue shifted with respect to the gas phase by .apprx.0. ...
In Ar matrix reversible aggregation of Au atoms to Au2 and Au3 clusters and dissocn. to monomers and in Xe matrix the formation of a special AunXe complex is obsd. The conversion ratios reach 103 and the aggregation efficiencies show thresholds and a progr ...
The reaction I2M + hn -> I2(B,v',j') + M (M = rare gas atom) was studied exptl. for excitation above the dissocn. limit of the I2M B state. A surprisingly large amt. of the available energy is found as relative translational energy of the I2 and M products ...
Fluorescence spectra from the Rydberg A2S+(v = 0) level of NO trapped in Ne, Ar, Kr, and Xe matrixes were obtained for 2 different sites. The main site is characterized by broad A(0,v'') bands (full width at half max. .simeq. 80 meV), blue gas-to-matrix sh ...
Recent work on the spectroscopic and photophys. properties of the excited states of Cl2 trapped in an Ar matrix is compared with independent gas-phase results on Cl2 + rare gas as well as with other matrix studies. An alternative interpretation of the resu ...
The efficiency of conventional aerodynamic isotope sepn. can be improved by 2 orders of magnitude with the aid of a relatively weak cw IR laser which is used to induce isotopically selective condensation. Overall isotope enrichment factors in excess of 2 a ...
Several new progressions consisting of broadbands were obsd. in the absorption spectra of NO trapped in rare gas matrixes. They were identified as the blue shifted transitions to the n = 3 (A 2S+, C 2P, D 2S+) and n = 4 (E 2S+, K 2P, M 2S+) Rydberg states ...
Selective IR vibrational predissocn. (IRVP) of van der Waals clusters in a free jet is an effective way to sep. isotopes. Abs. sepn. factors a in excess of 1.1 were obsd. upon irradn. of a beam of SF6 dild. in Ar with a 20 W CO2 laser. Selection of the wav ...
The photolytic cage effect was studied over a wide d. range of several bath gases in the laser flash photolysis of I2 at 694.3 nm. Particular attention was paid to measurements in the simple solvents Xe and Kr, which were compared with mol. dynamics calcns ...
