Picosecond time resolved Raman spectroscopy is a newly developed technique in chemical kinetics.

We report the first picosecond time resolved Raman spectra of myoglobin (Mb) generated with Soret excitation.

We report the first picosecond time resolved Raman spectra of hemoglobin (Hb) generated with blue picosecond pulses (20- 30 ps) that are both resonant with the Soret band and of sufficient intensi

We report direct measurements of drift velocities of photoexcited minority electrons in p-doped quantum well structures of GaAs/Al (0.48)Ga(0.52)As, using picosecond time-of-flight techniques.

An apparatus to probe picosecond photoinduced absorption in semiconductors between 2 microns and 5 microns with picosecond resolution is described.

Low concentrations of electrons in molten alkali halides form localized states similar to F-centers.

An apparatus is described which generates very sensitive picosecond transient Raman spectra with 5 ps time resolution.

In early work in picture coding, Graham stressed the role of the viewer and Powers and Staras concluded t h a t if large reductions in bit-rate are to be achieved they must come from "nonstatistica

The transmission of still pictures by the method of time modulation is investigated and found to be not only entirely practicable but also to provide pictures over line and by short-wave transmissi

The silicon target, used as the image sensing element in the Picturephone® camera tube, 1-4 is composed of a matrix of diffused diodes.
