rraman.t00B

rraman.t00B(t, Delta, eg, ee)

Time dependent overlap integral between vibrational ground states 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:

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