Das Absorptionsspektrum des ClF₃

Raman, infrared and ultraviolet spectra of the chlorine difluoride free radical in solid nitrogen

“…Figure 4(d) shows the spectrum of 5 mmol of sample deposited at 25 K. The absence of absorption maxima in the near-ultraviolet is consistent with the absorption spectrum of C1F3 gas. 13 Photolysis for two 20-min periods produced a broad weak absorption at 320 nm, Figure 4(e), which was markedly increased by temperature cycles to 40 and 45 K, Figure 4(f). Twenty more minutes of photolysis essentially destroyed the new 320-nm absorption, Figure 4(g); however, another 45-K temperature cycle restored the new band, Figure 4(h).…”

Structure of ClF3 and Exchange Studies on Some Halogen Fluorides by Nuclear Magnetic Resonance1

“…From the definitions of A and B A2 = 2 -SJ + 9/2/4 (12) and B2 = 2 + 5/ + 9/2/4 (13) Then B2 -A2 = 25/ (14) or 5 = (B2 -A2)/2/ (15) Substituting equations 15 and 14 into equation 12 we obtain A2 = (B2 -A2)2/4J2 -(B2 -A2)/2 + 9/2/4 (16) Solving for J2, we obtain…”

Halogen Fluorides And Other Covalent Fluorides - Physical And Chemical Properties

“…Chlorine trifluoride, like the monofluoride, has been widely studied spectroscopically. Its absorption spectrum in the visible and ultraviolet regions is known to be continuous (121), but despite several investigations (61,118) no satisfactory assignment of the observed Raman and infrared spectral lines has yet been made. These studies have, however, thrown considerable light on the possible structure of chlorine trifluoride and may also provide further evidence of association in the liquid state.…”
