rraman.molarExtinction2AbsCS

rraman.molarExtinction2AbsCS(eSpctr, IOR)

Convert molar extinction (cm-1 / M) to molecular absorption cross section (A**2 / molec).

See McHale, Resonance Raman Spectroscopy, Wiley, (2002), p. 545 or Myers & Mathies for details. The absorption cross section in solution has to be scaled by index of refraction unless the molar extinction has not been corrected.

Parameters:

• eSpctr (array) – Extinction spectrum in (cm-1 / M).
• IOR (float) – Index of refraction of surrounding solvent / medium.

Returns:

Absorption spectrum in units of (A**2 / molec.), same shape as eSpcrt.
