Notes: Abstract A small-signal gain in CO2 waveguide laser medium has been measured on rotational-vibrational transitions in the P-branch of the (0, 0, 1)-(0, 20, 0) band. It has been found that the rotational temperature is well defined in the waveguide laser system where high excitation power is injected and a large amount of energy is flowing through vibrational, rotational, and translational degrees of freedom. The rotational temperature is slightly higher than the translational temperature.

Notes: High performance thin-layer chromatography (HPTLC) was used to determine 12 metabolites of the tryptophan-NAD pathway in rat urine. The method of separation described in the previous report was improved. The metabolites were separated on the cellulose plate by using five multiple developments with four solvent systems. The plate was scanned by the TLC scanner at 254 nm and the amounts of the metabolites were calculated by comparing peak areas of the scanning curves obtained for the urine sample and for the authentic standards. This procedure can be used as a semiquantitative determination method for the metabolites in biological fluids.
