Wavelength-Wavenumber Conversion Table

Energy conversion table. Values of photon (vacuum) wavelength (nm), wavenumber (1 cm-1), frequency (THz) and energy (eV, J), as well as the energy per mole (J mol-1) of a chemical reaction can be easily converted if a ruler is placed horizontally over the chart. The bandgaps of different semiconductors are also indicated, as well as the wavelength of the intensity peak of a blackbody radiation for different temperatures. 

The following table provides a conversion between wavelength and wavenumber units, for use in infrared spectrophotometry. 

Most optical data are presented in graphical form as a function of wavelength. In some cases, wavenumber or photon energy are the independent variables, but conversion tables (Appendix A) will facilitate the use of these graphs. Optical terms are defined in Appendix B.

WAVELENGTH-WAVENUMBER CONVERSION TABLE Thomas J. Bruno and Paris D. N Svoronos... 

The following table provides a conversion between wavelength and wavenumber units, for use in infrared spectrophotometry (Refs. 1 and 2). Because spectra are presented in different formats, this table is an aid in interpretation. 

The spectral domains of UV radiation discussed in Fig. 3-9 and the corresponding energy conversions according to Eq. 3-3 are summarized in Tab. 3-3. In addition, this table contains information about the emission hnes of several types of lamp that are of interest to photochemical AOPs. Photochemists usually use the energy unit kj moh, whereas physicists prefer the unit eV (electron volt), and spectroscopists are used to wavenumber a=l/X in cm instead of wavelength. 

The different types of outer shell electronic transitions that occur by absorption or emission of electromagnetic radiation in the UV, Visible and Near IR spectral regions are summarized in Figure 2.1. Since the electronic spectra can be plotted as a function of wavelength (nm), wavenumber (cm" ) or energy (eV), the conversion factors between the various units are reported in Table 2.1.
