Vibration-Rotation Spectrum of HBr

1. Label the absorption lines with vibrational and rotational quantum numbers.
   用振动和旋转量子数标记吸收线
2. Explain why there is a missing line in the center.
   解释为什么中心处有一条缺失的线。
3. Determine the force constant for this molecule as accurately as you can from this data.
   根据此数据尽可能准确地确定该分子的力常数。
4. Determine the bond length of the HBr molecule and compare with a standard value.
   确定HBr分子的键长，并与标准值进行比较。
5. Explain why the lines intensities peak as they move away from the center and then diminish. See if you can use the internsities to estimate the temperature of this sample.
   解释为什么这些线条的强度在远离中心时达到峰值然后减弱。尝试利用这些强度来估计样品的温度。
6. Explain why the lines to the left of center are further apart in energy than the lines to the right.
   解释为什么在中心左侧的线条在能量上比右侧的线条更分散。
