Near-infrared diode laser spectroscopy of free radicals.
Spectroscopic results on the radicals HCSi, CCO, and FeC obtained by studying in detail energy level structures using 0.8 microm diode laser system are reported. Of these radicals, the CCO radical was investigated mainly using Fabry-Perot type diode lasers with inconvenient mode gaps in the early stage of our near-infrared diode laser spectroscopic study of free radicals, and on the other hand, the FeC and HCSi radicals were studied using an external cavity diode laser. For the FeC radical, which is an interesting radical composed of an iron atom having 3d electrons, information on spin-orbit interaction between the triplet electronic ground state and a low-lying singlet electronic excited state is reported somewhat in detail. For the HCSi and CCO radicals, spectral particularities produced by a Renner-Teller interaction and a spin-orbit interaction are described for their high-resolution spectroscopic interest.
Near-Infrared Diode Laser Spectroscopy of the Nitrogen Molecule in Rydberg State: Analysis of thec1Πu−a″1Σg+,v= 1–0 Band
Abstract A new singlet-singlet absorption band between Rydberg states of the nitrogen molecule was studied by near-infrared diode laser spectroscopy in the 1.3 μm region. An analysis was made for the band to establish line assignments and determine molecular parameters for both the lower and the upper vibronic states. As a result of the analysis, this band was assigned to the c 1 Π u –a ″ 1 Σ g + , v = 1–0 band. The anomaly of the Λ-type doubling structure in the c 1 Π u ( v = 1) state was discussed in connection with the interaction with the b ′ 1 Σ u + (v = 4) state. The predissociation in the c 1 Π u ( v = 1) state was also discussed relating with the line broadening observed.
Comparative Industrial Sociology and the Convergence Hypothesis
Industrial sociology grew spectacularly after World War II, concentrating on three areas: workers' relations with each other, their managers, and their unions; the social organization of the factory; and the impact of technology on social systems extending from the factory to the society. Unable to sus­ tain leadership in all of these areas, industrial sociology shrivelled as other fields invaded its domains. Human relations became the ideological property of the business schools; labor economics maintained its grip on industrial relations; industry-community relations waned as interest in community power soared; industrial organizations were absorbed into the study of com­ plex organizations; occupational sociology maintained research impetus in labor force analysis; and the sociology of the economy dominated the study of industry's institutional relationships. Industrial sociology survived on remnants: worker-machine relationships (job satisfaction, alienation, un­ employment), organizational responses to technological changes. and a bit of working-class ethnology. Enduring interest in technology, however, en­ abled industrial sociology to take part in sociology's expanding interest in comparative studies.
