摘要:

The diffuse reflectance spectrum of cupric oxide (GuO) powder in the region 300–1000 mμ. has already been studied1,2. In the present communication, the diffuse reflectance spectra of both pure and diluted cupric oxide powder samples have been reported. In the present work, the region of investigation has also been extended down to 200 mμ.

摘要:

The absorption spectra of hexafluoro 1,3-butadiene and 1,3-butadiene were measured from 2500Å to 1150Å. The effects of perfluorination on the spectra are discussed in the light of previous studies and recent calculations.

摘要:

An analytical method based on emission spectrography is described for the determination of the following trace elements: Ba, Co, Cr, Mn, Ni, Sc, Ti and V in CaO-matrix. The calibration curves have been constructed using the least squares method and the data treated statistically. Finally, the limits of detection, 1imits of guarantee for purity, and the precision of the method have been calculated.

摘要:

Normal vibrations, of spherical top molecules or ions of XY6type belonging to Ohsymmetry, have been studied by a number of workers1,2. Cut of the six fundamentals, that they are known to possess3, a set of three gerade modes ν1(a1g), ν2(eg) and ν5(f2g) are Raman active while a set of two—ν3and ν4(f1u) are infrared active while ν6(f2u) is inactive in both Raman and infrared, though it may appear in combination. ν1, ν2and ν3, fundamentals involve stretching of the X-Y bond while the remaining three ν4, ν5and ν6fundamentals are primarily associated With skeletal deformations due to Y-X-Y bending modes. Thus symmetry distribution of vibrations of such molecules or ions in this point group is given by
