spectral data (IR, NMR and Mass). X-ray crystallographic studies of representative compound 6b have been reported. DFT studies were carried out on indazole derivative and its regioisomer for validation of the assigned structure. Also experimental NMR is correlated with that obtained from theoretical studies. Photo physical (UV and fluorescence) studies of compounds 4 and 6 have also been reported.
