- Properties of Bromine Two isotopes, 79 Br and 81 Br ~50/50 of each isotope Nuclear spin of 3/2 for both isotopes

- A closer view
- Slide 10
- Ground State a) Y. Niide, M, Takano,T. Satoh, and Y. Sasada J. Mol. Spectrosc., 63, 108(1976)
- Slide 11
- Vibrationally Excited States ~110 cm -1 ~247 cm -1 ~386 cm -1
- Slide 12
- 21 =1 a) Y. Niide, M, Takano, T. Satoh, and Y. Sasada J. Mol. Spectrosc., 75, 87(1979) * Taken from ground state values
- Slide 13
- 21 =2 a) Y. Niide, M, Takano, T. Satoh, and Y. Sasada J. Mol. Spectrosc., 75, 87(1979) * Taken from ground state values
- Slide 14
- Residuals
- Slide 15
- Conclusions and Future Work The ground state and v=1 and v=2 excited states of 21 were found and fit 916 out of 2579 (35%) peaks assigned Look for v=3 for 21 v=1 20 cis (maybe with more averaging)
