Phys., 22, 790-795, (1954); http://link.aip.org/link/doi/10.1063/1.1740194 Data: diagram, table Energy/Wavelength range: 204 - 260 nm Resolution: Temperature: 303 K Temperature dependence: Pressure/Concentration: Phase: pH: Comments: A comparison of the continuous ultraviolet absorption spectra of CH3Br and CD3Br indicated a nearly constant shift of + 280 ± 50 cm-1 upon deuterium substitution. In the case of CHCl3 and CDCl3 the shift was less than the uncertainty of ± 50 cm-1. The ultraviolet absorption spectra of CCl4, CFCl3, CH2Cl2, CF2Cl2, and CHFCl2 are also reported.
