Abstract

3-methoxy-4-hydroxy-benzaldehyde (MHBA) single crystals were grown by slow evaporation method using ethyl acetate as a solvent. The grown crystals were pale yellow in colour. The obtained crystal was subjected to single crystal X-ray diffraction analysis to determine the cell parameters. The functional groups of the grown crystal have been identified by both FT-IR and FT-Raman analyses. Thermal analysis done on the crystal reveals the decomposition and melting point of the grown crystals. From the absorption study it was found that the lower cut off wavelength value is about 370 nm and hence it suggests that the crystal is transparent in UV-Visible region. Using Brewster angle’s method the refractive index of MHBA was calculated. From the NLO results, it has been proved that MHBA is a promising candidate of frequency-doubling laser material. The dielectric constant and dielectric loss of the grown crystal also have been measured..
