A number of complexes in the series (Cu LL'),, where L = [(CH,),C-CO-CH-COC( CH,),]-I and L'= 3-(Me) C6H,0-, 2,6-(Di-Me)C6H30-, 4-(OH)C6H?O-, 3- (F) C6H,0-, 4-(Br)C6H40-a, nd 3,s-(Dl-Me)C6H30h- ave been prepared and theu magnetic and optical properties determined. In chloroform, the complexes exhibit two bands in the visible and near UV regions. All complexes show room temperature magnetic ...

The effect of solvents on photophysical properties namely absorption transition energy, fluorescence transition energy and stoke’s shift of a ketocyanine dye 2,5-di[(E)-1-(4 aminophenyl) methylidine]-1cyclopentanone (2,5-APMC) is analyzed using Lippert-Mataga bulk polarity function, Reichardt’s microscopic solvent polarity parameter and Kamlet’s multiple linear regression approach. The spectral...

Highly accurate soft-XMCD data recorded on a Nd2Fe14B single crystal, through the spin reorientation transition show that the average Fe orbital moment (a) is proportional to the macroscopic Fe anisotropy constant, and (b) diverges 15 K below the reorientation transition temperature. This divergence is indicative of a critical behavior and it is related to a tetragonal distortion. These results...

Line strengths have been calculated in the form of Einstein A coefficients and f-values for a large number of bands of the A2Π–X2Σ+ and B2Σ+–X2Σ+ systems and rovibrational transitions within the X2Σ+ state of CN using Western’s pgopher program. The J dependence of the transition dipole moment matrix elements (the Herman–Wallis effect) has been taken into account. Rydberg–Klein–Rees potential en...

Band-integrated oscillator strengths of the CO A1Π− X1Σ+ transition for 0 ≤ v′ ≤ 23 and v′′ = 0− 1 have been calculated from an ab initio dipole transition moment given by highly correlated electronic wave functions. The calculations were carefully optimized to represent the dipole transition moment in the large range of internuclear distances necessary to describe correctly high vibrational le...
