Three-Pulse Echo Peak Shift Studies of Polar Solvation Dynamics

The three-pulse photon echo peak shift technique is used to study room temperature solvation dynamics in acetonitrile, benzonitrile, methanol, ethanol, ethylene glycol, and chloroform utilizing the tricarbocyanine dye, IR144 as the probe molecule. In all cases, an ultrafast component, ascribed to inertial solvent motion, was evident after the very rapid dephasing of the intramolecular vibration...

Two-color three pulse photon echo peak shift spectroscopy

Two-color three pulse photon echo peak shift spectroscopy ͑2C3PEPS͒ has been used to probe correlation in electronic transitions in two different regions of the electronic spectrum of a chromophore in the condensed phase. The 2C3PEPS can be done in an ''uphill'' or a ''downhill'' sense, where the first two interactions are of lower ͑higher͒ frequency than the final interaction with the radiation fi...

Ambient Volume Scattering — Supplemental Results

In this supplementary section, we qualitatively compare the illumination effects and the bias of ambient volume scattering with full global volume illumination. For comparison, we employ a CUDA-accelerated implementation of path tracing for participating media [1] with light source sampling to solve the radiative transfer equation accurately, using the same hardware as in the main paper (Intel ...

Amplifying volume in scattering media.

We investigate the influence of the excitation spot diameter on the laser threshold of a scattering amplifying medium. Fluorescence spectra are recorded from a suspension of TiO(2) scatterers in Sulforhodamine B dye. The threshold pump intensity becomes larger by a factor of 70 if the excitation beam diameter gets close to the mean free path?. This increase is explained by use of a simple model...
