Dynamically skewed lines: rotations in superfluid helium.

Dynamically skewed spectral lines arise for chirped damped oscillators. We extend this to the chirped damped rotor and apply it to treat the rovibrational line shapes of small molecules isolated in superfluid helium. The simple analysis generates valuable physical insights on the prevailing dynamics of a rotor coupled to its environment.

Solidlike coherent vibronic dynamics in a room temperature liquid: Resonant Raman and absorption spectroscopy of liquid bromine.

UV-visible absorption and resonance Raman (RR) spectra of liquid bromine are presented and rigorously interpreted. The RR spectra, which show an anharmonic vibrational progression of up to 30 overtones, define the ground state potential in the range 2.05 A View Article and Find Full Text PDF
