rraman.applyInhomogeneousBroadening

rraman.applyInhomogeneousBroadening(wn, y, sig, alpha=1)

Convolute a spectrum with a Gaussian/Lorentzian to account for inhomogeneous broadening.

Parameters:

• wn (array) – Frequency axis in same units as sig (cm-1).
• y (array) – Input spectrum, same shape as wn.
• sig (float) – Width of convolution function in same units as x (standard deviation of Gaussian distribution). Must not be zero.
• alpha (float) –

  Lineshape parameter:

  • 1 = Gaussian,
  • 0 = Lorentzian.

Returns:

Convoluted spectrum (same shape as y).
