In spant: MR Spectroscopy Analysis Tools

Generate an asymmetric pseudo-Voigt resonance in the frequency domain.

Description

Method is described in detail by Stancik AL and Brauns EB: "A simple asymmetric lineshape for fitting infrared absorption spectra." Vib Spectrosc. 2008; 47: 66-69.

Usage

sim_asy_pvoigt(
  freq = 0,
  fwhm = 0,
  lg = 0,
  asy = 0,
  acq_paras = def_acq_paras(),
  gen_im_pts = FALSE
)

Arguments

freq	resonance frequency in ppm.
fwhm	resonance FWHM.
lg	Lorentz-Gauss lineshape parameter (between 0 and 1).
asy	asymmetry parameter.
acq_paras	list of acquisition parameters. See def_acq_paras
gen_im_pts	option to generate imaginary data points, defaults to FALSE.
