The formation of sub-micron sized particulates has been studied in a low pressure (0.1 mbar) radio-frequency (13.56 MHz) capacitively coupled plasma discharge. Particles are studied in situ by infrared absorption spectroscopy, laser illumination and Cavity ...
Low-temp. gas-phase wavelengths and bandwidths for astronomical searches for C60 in the 2400-4100 Å region are detd. from the absorption spectra of C60 in rare gas matrixes at 4 K, coupled with information on the dependence of the vibronic transition frequ ...
The structural changes due to formation of electronic bubbles in solid D2 are studied by fluorescence, fluorescence-excitation, and fluorescence-depletion spectroscopy of the lowest Rydberg state, A 2S+(3ss), of the NO impurity. The A X band is strongly bl ...
The ultrafast dynamics of electronic bubble formation upon excitation of the A(3ss) Rydberg state of NO trapped in solid H2 and D2 was studied by femtosecond pump-probe spectroscopy. The evolution of the spherical bubble is followed in real time by a probe ...
The absorption and emission spectra of the 3P1-1S0 transition of a Hg atom embedded in solid Ar were simulated using the mol. dynamics with quantum transitions algorithm to consider the nonadiabatic transitions between the three adiabatic states. The simul ...
A technique for high resoln. anion photodetachment spectroscopy is presented that combines velocity map imaging and anion threshold photodetachment. This method, slow electron velocity-map imaging, provides spectral line widths of better than 1 meV. Spectr ...
The dynamics of electron bubble formation upon excitation of the A(3ss) Rydberg orbital of NO in solid Ne was studied by conventional spectroscopy and fs pump-probe spectroscopy. The fs pump pulse initiates the formation of a bubble by the expansion of the ...
The absorption spectrum of C60 embedded in Ne matrixes in the 410-360 nm region is revisited. A complete assignment of the absorption lines therein is proposed in terms of transition to the ungerade states 1 1G1u, 1 1T1u and 2 1T1u states, with progression ...
A review with 30 refs. on some of the authors works on the absorption, excitation and emission spectra of C60 embedded in rare gas matrixes while stressing the role of the environment. The gas phase resonant 2-photon ionization spectrum of C60 is reanalyze ...
We calc. the effects of relatively strong elec. fields, corresponding to typical values for the fields inside glasses and proteins, on the spectroscopic properties of a simple two-level mol. Disorder in the elec. field strength is employed as a phys. sourc ...
