Stimulated Raman

We apply femtosecond-infrared pump- stimulated Raman probe spectroscopy (fs-IR-SRS) which provides sub-100 fs time resolution, spectral resolution better than 10 cm-1 and the 100 cm-1 to 4000 cm-1 probe bandwidth to study vibrational relaxation pathway after vibrational excitation of OH stretching mode in HDO in the system composed of 30 % of HDO in D2O.

The efficiency of the stimulated Raman gain scattering (SRGS) in liquids is sufficiently high to make the phenomenon useful as a means of chemical analysis. Quantitative and qualitative studies of stimulated Raman gain detected by photothermal probe beam deflection are presented with a major simplification in instrumentation for generating the Stokes probe beam. This technique is evaluated for the detection and quantitation of a model chlorinated hydrocarbon, 1,1,1-trichloroethane. With a very modest laser pulse energy of 1.5 mJ (average power of 1.5 mW) and a pathlength of 10 cm, the technique is useful for the noninvasive, real-time monitoring of SRGS-active compounds at the 10 mM level. Selectivity against 1,1,2-trichloroethane, 1,2-dichloroethane, trichloroethylene, ethylbenzene, and benzene is excellent. Direct identification and simultaneous determination of individual compounds in process and effluent streams could be attained without sampling, separations, or other pretreatment procedures.

SummaryThe addition of small amounts of extrinsic thromboplastin or of thrombin to blood in vitro accelerated coagulation more frequently and to a greater extent when determined by the flowing time test than when measured by the silicone clotting time, or by the blood or plasma heparin tolerance tests. Similar results were obtained when intrinsic thromboplastin formation was stimulated by contact with glass. However there was little or no acceleration of the flowing clotting time of plasma obtained from aliquots of the thromboplastin-containing blood. These results indicate that the flowing clotting time (thrombus formation time) of whole blcod is a more reliable test of hypercoagulability than previously described blood or plasma clotting time tests.
