rraman.t20B

rraman.t20B(t, Delta, eg, ee)

Time dependent overlap integral between vibrational ground and second excited state of electronic ground and excited state with different ground and excited state vibrational frequencies.

Parameters:

• t (array) – Time axis in (fs).
• Delta (float) – Displacement of excited state potential energy surface along this vibrational coordinate in dimensionless coordinates.
• eg (float) – Vibrational frequency in the ground state (cm-1).
• ee (float) – Vibrational frequency in the excited state (cm-1).

Returns:

2-0 overlap integral as function of time (same shape as t).
