Ir spec for benzene
WebNov 9, 2024 · The abscissa of our IR diagrams shows the wavenumbers, and the boundary is at a value of 1500 cm‾¹. So we can also draw the line at a value of 1500 cm‾¹ when we interpret spectrum. When we look at the following table of the characteristic stretching wavenumber values for the bonds, we can see that the most absorbing in the region … Web43 rows · The IR Spectrum Table is a chart for use during infrared spectroscopy.
