Wolfgang W. Osterhageely that the lower energy rotational transitions should be accessible with one of the optically pumped lasers. Several r.f. transition frequencies have been calculated for HO. from the constants determined by LMR and are listed by Hougen et al. . The most accurate predictions are for transition, inv

Wolfgang W. Osterhage its main drawback was a lack of sufficiently intense radiation sources. The introduction of lasers, therefore, has indeed revolutionized this classical field of spectroscopy. Lasers have not only greatly enhanced the sensitivity of spontaneous Raman spectroscopy but they have furthermore initiated
