(a) IR spectra of PHEN form I and PHEN solutions in different solvents; (b)–(g) IR spectra of PHEN solutions in acetonitrile, methanol, DMSO, toluene, chloroform and DMA at different concentrations; (h) FTIR data of PHEN and PHEN in chloroform at different concentrations; (i) FTIR data of PHEN and PHEN in DMA at different concentrations. The solvent spectrum has been subtracted from all the solution spectra. |
