Liquid and solid phase Raman spectra of bromine and carbon disulfide were obtained at high pressure in the diamond cell. Single crystals of both compounds were grown under high pressure and polarized Raman spectra obtained. These spectra indicate tha

A strain gage transducer system has been developed which functions as ’’electronic calipers’’ to measure changes in thickness of samples as they are compressed in an opposed diamond‐anvil optical cell. Planimeter measurements on photomicrog

Infrared diffuse reflectance spectra were recorded for the 22 tetrachlorodibenzodioxin isomers (TCDDs). By use of micro-DRIFT techniques and signal averaging, identifiable spectra for each of the isomers were achieved at low nanogram levels. Spectral

Four different types of ir experiments, involving changes in pH, changes in pressure, and the use of nonaqueous solvents, and with either albumin molecules dissolved in saline or adsorbed albumin films, support the hypothesis that the bandwidth of th

Micro-diffuse reflectance Fourier transform infrared (DRIFT) and matrix isolation (MI) Fourier transform infrared spectra of the 22 tetrachlorodibenzodioxin (TCDD) isomers have been recorded. The DRIFT and MI techniques required about four minutes an

Far infrared spectra of the series of n-alkyl acids from propanoic to undecanoic were obtained in both the liquid and solid states. The hydrogen bond stretching vibration of the liquid acids has been observed and assigned. From the solid state spectr

The far‐infrared spectra (600–60 cm−1) of HgCl2, HgBr2, HgI2 (red), and their one‐to‐one p‐dioxane complexes (in the solid state) were investigated. All of the observed spectra, except those of HgI2, were assigned on the base of the symme

A diamond-window high pressure cell has been used to study the effects of pressure on the OH stretching vibration of liquid alcohols. The results of this study show that: (1) while decreasing temperature changes the polymer equilibrium of hydrogen bo
