Run the Quick Start example from the RADIS documentation
Run the different Cells with the Run command above (or Cell/Runs All). First, let's calculate a CO spectrum under thermal equilibrium at 1000 K.
%matplotlib inline
from radis import calc_spectrum
s = calc_spectrum(1900, 2300, # cm-1
molecule='CO',
isotope='1,2,3',
pressure=1.01325, # bar
Tgas=1000, # K
mole_fraction=0.1,
path_length=1, # cm
)
s.apply_slit(0.5, 'nm')
s.plot('radiance')
See the RADIS Documentation: Spectrum how to? for more post-processing methods
Below, we calculate a Nonequilibrium spectrum. Rovibrational energies will be calculated automatically from RADIS built-in spectroscopic constants
s2 = calc_spectrum(1900, 2300, # cm-1
molecule='CO',
isotope='1,2,3',
pressure=1.01325, # bar
Tvib=1000, # K
Trot=300, # K
mole_fraction=0.1,
path_length=1, # cm
)
s2.apply_slit(0.5, 'nm')
s2.plot('radiance')
Now calculate your own spectra:
