Pressure <-> Ruby Raman shift

Parameters from DOI: 10.1063/1.2135877

Usage

Pruby(w, laser = 532, P = -1, w0 = -1, l = FALSE)

Arguments

w

Position of the R2 ruby line in cm-1

laser

laser wavelength in nm (default=532)

P

Pressure in GPa (default=-1). If P>0, will return the expected position of the R2 line in cm-1

w0

Position of the R2 ruby line in cm-1 at P=0 (default=-1).
If w0>0, corrects for potential strain in the ruby. Otherwise, uses the references lambda0 = 694.24 nm

l

TRUE or FALSE (default). If TRUE and P>0, returns the expected position of the R2 line in nm instead of cm-1.

Value

Examples

Pruby(P = 1) # returns expected R2 position in cm-1
#> [1] 4400.406
Pruby(w = 4401) # return corresponding pressure in GPa
#> [1] 1.077842
