Abstract :
In this work, an organic crystal ,synthesis of N-(tert-butyl)-2-(4-nitrophenyl)imidazo[1,2-a]pyrazin-3-amine.vibration modes were assigned using FT-IR and FT-Raman spectra Raman spectra correlate very well with the structural data and illustrate the subtitle choice of the ligands, used can affect the vibrational characteristics of the Mo-o bonds Fourier Transform Infrared (FT-IR) spectral studies have been carried out, to confirm the presence of various functional group .The UV-Vis-NIR spectrum suggests the suitability of crystal for various optical application properties were investigated using the result of UV-Vis study showed that the crystal was about 50% transparent in the visible region. The grown crystal exhibits some excellent characteristics including wide optical transparency in the region (210-1100nm).ultraviolet wavelength emission .The optical transmittance of the crystal was ascertained by recording Mass spectroscopy. TGA/DSC analysis. Third order optical properties nonlinear absorption coefficient. non-linear refractive index and third order non-linear susceptibility was calculated by z-scan method using 632.8nm He-Ne laser. The thermo gravimetric Analysis (TGA) and Differential Scanning Calorimeter (DSC) were carried out to establish the thermal stability of the crystal .The 1H and C13 nuclear magnetic resonance spectra were recorded to establish the molecular structure of the crystal. The crystal structure was confirmed by Single Crystal x-ray diffraction.
