Electrostatic Perturbation

The optical absorption of a single crystal of VSO4.7H2O was measured in the range 9000–35,000 cm−1. The three observed bands were assigned to transitions between the four orbital levels resulting from cubic electrostatic perturbation of the spherical terms of configuration 3d3. Values of Dq = 1200 cm−1 and E = 10,000 cm−1 were derived from the spectral analysis.

Decay Times

The polarized optical absorption and emission (spectra, decay times) of single-crystal [lr(CO)2mnt] TBA at temperatures 2 K≦T≤295 K and homogeneous magnetic fields O≦H≦6T are reported. The highly resolved spectra show 0-0 transitions with vibrational satellites and phonon side bands. Applied magnetic fields yield no effect on the emission. The lowest excited electronic states can be assigned to the spin-orbit components A′1 B′1 and B′1 of the charge transfer triplet 3A2 (symmetry C2v)

Raman Spectral Analysis

ABSTRACT Organic single crystal of Phthalic Anhydride (PA) was successfully grown by slow evaporation method. The structure of the grown crystal was confirmed by X-ray diffraction analysis. FT-IR, and FT-Raman spectral analysis of the crystalline samples reveal that the crystalline sample consists of all functional groups. The placement of protons was identified from H1-NMR spectral analysis. UV-Visible and photoluminescence spectral analyses were carried out for the grown crystals. The thermal behavior was studied with TGA-DTA analyses. The existence of second harmonic generation (SHG) signal was observed using Nd:YAG laser with a fundamental wavelength of 1064 nm.
