By clicking on any of the five structural names in the first column, a corresponding spectrum will be displayed beneath the table stretching vibrations.
Structure of 1-naphthol/alcohol clusters studied by ir dip spectroscopy and ab initio molecular orbital calculations the ir spectrum of cis-1-naphthol,. The normal way to approach interpretation of an ir spectrum is to examine the functional group region to (alcohol) 3300-3600 cm-1 monomeric forms. Ir spectrum: the ir spectrum for the t-pentyl alcohol shows a specific peak at approximately 3400 wavenumbers this is due to the o-h functional group this peak. Notice: except where noted, spectra from this collection were measured on dispersive instruments, often in carefully selected solvents, and hence may differ in detail.
