Crystal growth, spectroscopic and theoretical investigation of nonlinear optical 2‑bromo-4-nitroaniline single crystals for NLO and optoelectronic applications

A novel stilbazolium derivative crystals of 4-[2-(4-dimethyl amino-phenyl)-vinyl]-1-methyl-pyridinium+ bromide− (DMSB) single crystal: exploration of the growth, molecular structure, linear optical, and third order nonlinear properties

“…The characteristic peak of the C–Br stretching is observed at 573 cm −1 , which is determined to be the bromide anion in the DMSB crystal. 35 Identification of all the observed functional groups concluded that the DMSB compound was formed. The summary of the FTIR peaks and their assignments are tabulated in Table 6 .…”
