We have successfully used phase matching considerations to provide significant discrimination against cascaded lower-order responses and measured the direct fifth-order response from the intermolecular motions in liquid CS2. Here we report the measured polarized and magic angle responses and discuss comparisons

Vibrational Spectra of Tetraphosphorus Tetrasulphides The solid-state i.r. and Raman spectra of the crystalline tetraphosphorus tetrasulphides — 0C-P4S4 and ß-V/jß^ — and the Raman spectrum of the 0C-P4S4 melt have been recorded. The observed frequencies of 0C-P4S4 were tentatively assigned to P4S4 molecules of the cradle type, possessing Ü2d symmetry. An assignment of the /9-P4S4 frequencies t...

Prof. Raman found that the Indian drums all produced harmonics, whereas the western drums do not, a fact that is proved theoretically. He also found that that the density distribution present as a central black patch on the Indian drums is not of the type r. However, R.Siddharthan, P.Chatterjee and Vikram Tripathi have stated in their paper 1 that they found the harmonics of the Indian Drums al...
