The dynamic FTIR spectra of propanol in the argon matrix have been measured using a thermal perturbation by heating sample from T = 11 K to 30 stepping 1 K. 2D Fourier-transform infrared (FTIR) absorption correlation analysis has carried out, main attention being concentrated region O–H stretching vibrations at 3000–3700 cm–1. peaks monomers, two conformers open dimer, and cyclic structures dim...
