Summary

One of the functions of Stevenson is a constant multiple of one of the functions of Muschelisvili and the derivative of the second function of Stevenson is a constant multiple of the second function of Mukhelisvili. [...] In order to find out whether in a di-substituted benzene compound the relative positions of the two substitution groups have an influence on the number and positions of the new lines in the low frequency region which may appear in the Raman spectra of these substances in the solid state the Raman spectra of ortho-and parachlorotoluene in the solid state have been studied in the present imPestigat [...] In this paper an attempt is made to carry the problem a step further and also to find out the effect of the viscosity of the liquid and radius of the tube on the stream line motion of the liquid. [...] The absorption spectra of phenetole in the liquid and solid states and those of n-butylbenzoate in the vapour liquid and solid phases have been photographed in the region between 2820 and 25oo A. U. using thin films of the substances in the case of the licpaid and solid phases In the absorption spectrum of phenetole in the liquid state at ;3o°C three broad bands are observed with the vband a [...] The length of the of the absorption tube used in the investigation of the spectrum of n-butylbenzoate in the vapour state was 90 cm the ends being closed by quartz windows sealed with sodium silicate cement.
