Ultrafast photochemical reactions in liquids occur on similar or shorter time scales compared
to the equilibration of the optically populated excited state. This equilibration involves the …

It is well-known that the solvent can strongly influence the course, rate, and equilibrium
position of many chemical reactions. 1, 2 The position and intensity of the bands in the …

Chemical and physical systems undergoing change display spectral signatures from the
radio frequency to the X-ray region of the electromagnetic spectrum. This has led to the …

Terahertz spectroscopy emerged about 13 years ago with the demonstration that nearly
single-cycle pulses of far-infrared radiation could be generated, propagated through free …

Solutions of the zwitterionic betaine dye 2, 6-diphenyl-4-(2, 4, 6-triphenylpyridinium-1-yl)
phenolate are solvatochromic, thermochromic, piezochromic, and halochromic. That is, the …

This short overview describes the historical development of the physics and chemistry of
organic solvents and solutions from the alchemist era until the present time based on some …

It is shown that the laser induced ultrafast demagnetization of ferromagnetic films results in
the emission of a terahertz electromagnetic pulse. This emission has been detected from Ni …

The desire to quantify the presence of analytes within diverse physiological, environmental
and industrial systems has led to the development of many novel detection methods. In this …

Solutions of the zwitterionic betaine dye 4-(2, 4, 6-triphenylpyridinium-1-yl)-2, 6-di-
