Doppler measurements, using the Capri magnetograph, of the latitudinal fine structure of the solar differential rotation have been carried out. The positions of the photospheric lines C I 5380.32 and Fe I 5364.88 have been simultaneously recorded. In contrast to Gilman's model (1972) which predicted an equatorial deceleration of the differential

Submillimeter observations made with a rapid-scanning interferometer during the solar eclipse of June 30, 1973 are reported. Reduction, correction, and plotting of the data is described, and the obtained results show that the spike can be identified with emission from chromospheric spicules. Models of spicules from optical wavelength data indicate

The paper describes some results and methods of work on the submillimeter spectrum and its application to atmospheric and astrophysical problems. The paper begins with descriptions of the spectroscopic techniques evolved and used, which provide spectral resolution more than half an order of magnitude finer than previously available, particularly at
