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 authors present mol. dynamics simulations of the absorption spectra of the Hg2 mol. in solid Ne, Ar, and Xe. The simulations were performed using classical mol. dynamics (MD) and a diat.-in-mols. (DIM) treatment of the mixing of the different states of ...
The authors present a new technique to record single x-ray pulses in time-resolved x-ray absorption spectra spectroscopy (XAS) expts. at low frequencies around 1 kHz compared to the multibunch repetition rate at synchrotron radiation storage rings of sever ...
Structural dynamics in solid hydrogens is impulsively triggered by femtosecond excitation of the lowest Rydberg state of the NO impurity. The resulting charge redistribution induces a local radial deformation of the medium ("bubble" formation) around the ...
We report on structural dynamics in simple van der Waals solids (Ar, Ne, and H2), as driven by the excitation of an impurity (NO) Rydberg state. The resulting charge redistribution induces a local radial deformation of the medium ("bubble" formation). Th ...
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 ...
Steady-state and picosecond (ps) fluorescence studies of wild-type bacteriorhodopsin (wt-bR) and of a nonisomerizing analog locked in the all-trans configuration have been performed. Extending earlier work done by femtosecond absorption spectroscopy, we ob ...
We report UV and visible mol. ion-pair emission upon 193 nm excitation of I2 in solid xenon. By comparison to mol. emission obsd. in Kr matrixes, it is assigned to the d(2u)->2g (I*+I) and d(2u)->2g (I+I) transitions. The solvation energy of this charge tr ...
The authors present the case for exploiting time-resolved x-ray absorption to study structural dynamics in the liq. phase. With this aim in mind and considering the large differences between absorption coeffs. in the optical and the x-ray domains as well a ...
