Experimental determination of refractive index of gas hydrates

Chemical Engineering Science, 1997
The refractive indexes of methane hydrate and natural gas hydrate have been experimentally determined. The refractive indexes were determined in an indirect manner making use of the fact that two non-absorbing materials will have the same refractive index if they cannot be distinguished visually.

Refractive index of a dilute Bose gas

Physical Review A, 1995
We derive the dispersion relation for the propagation of quasiresonant light with frequency ωL in an ultracold gas of bosonic atoms in the dilute regime, i.e., for an atomic density ρ0≪(ωL/c)3. In our calculation, valid up to order 2 in density, two types of corrections to the Lorentz-Lorenz formula for the refractive index appear. The first one is due

Use of the Retention Index in Gas Chromatographic Studies of Drugs

Journal of Analytical Toxicology, 1982
In earlier studies, it has been shown that the retention index (Ir) is a very reproducible measure of gas chromatographic mobility. Statistically comparing Ir values obtained here with those found in references has yielded very satisfying results. This will enable the use of Ir values in the screening phase of analysis for general unknowns using the ...

Refractive index of a vibrationally excited gas

Soviet Journal of Quantum Electronics, 1984
It has been established that the contribution made by vibrational excitation may be appreciable, particularly in the case of molecular polarizabilities, and should be taken into account when determining the temperature and density in nonequilibrium gases. The results are calculated for important molecules such as CO, CO2 and SF6.

Method of determining gas-transfer index

Soviet Mining Science, 1987
Determining the gas-transfer index of coal is investigated on the basis of the operation of the PGO-1 laboratory instrument. Its operating principles and construction are briefly described as is the method of measurement of the gas-transfer index. This method of measurement is determined in three successive operations, through use of a vacuum pump to ...
