  1. The Spectra and Dynamics of Diatomic Molecules 双原子分子光谱 Diatomic Molecular Spectroscopy （四） 马维光 量子光学与光量子器件国家重点实验室 山西大学物理电子工程学院 激光光谱研究室

  2. Before: Electric wavefunction under rigid molecule model; Now: 1, Turning to nonrigid molecule model to calculate the vibration and rotation of nucleis. 2, Determine the potential curve using the rotation vibration term values.

  3. These two equations are the basis for the exact treatment of rotation and vibration of diatomic molecules!

  4. Rigid rotor, centrifugal distortion Quadratically dependent on J. Level difference Linearly increasing with the number of J cm-1

  5. Kinetic and potential energy

  6. Term value

  7. assuming

  8. Term value

  9. 1.25e3 GHz/240m 670 MHz/450mm

  10. Most frequently used to find the constants using fitting procedure.

  11. condition

  12. R1 R2

  13. Most frequently used method to determine the potential curve! Applying WKB method to determine the turning points R1 and R2 from E(v,J)

  14. Calculating f and g from WKB Euler formula
