Linear Molecule State

This contains the rotational constants and other information specific to each state within a linear molecule. Note that PGOPHER will calculate Hund's cases (a) and (b) exactly; other cases can be handled with some restrictions.

Settings

Colour Colour - set to "None" to take value from elsewhere (from the molecule object, for example).
S Electron Spin
Lambda Electronic angular momentum - use Sigma-, Sigma+, Pi, Delta, Phi, Gamma, H, I or a numerical value
gerade true for gerade states; ignored if molecule is not symmetric.

Parameters

Origin State Origin.
Width Linewidth (rotation independent) for state.
B Rotational constant.
A Spin-orbit coupling constant.
LambdaSS Spin - spin coupling constant (=1.5*ε).
o Spin-spin coupling constant giving lambda doubling for Omega = 0 states.
theta Higher Order Spin-Spin interaction (S>=2 only).
Gamma Spin rotation coupling constant.
p Lambda doubling constant.
q Lambda doubling constant.
D Quartic centrifugal distortion.
H Sextic centrifugal distortion.
L J8 centrifugal distortion.
M J10 centrifugal distortion.
PP J12 centrifugal distortion. (Not P to avoid confusion with p.)
AD Centrifugal distortion of A.
LambdaD Centrifugal Distortion of Lambda.
LambdaH J^4 Centrifugal Distortion of Lambda.
oD Centrifugal distortion of o.
oH J4 Centrifugal distortion of o.
oL J6 Centrifugal distortion of o.
pD Centrifugal distortion of p.
pH J6 Centrifugal distortion of p.
pL J8 Centrifugal distortion of p.
qD Centrifugal distortion of q.
qH J6 Centrifugal distortion of q.
qL J8 Centrifugal distortion of q.
gammaD Centrifugal distortion of gamma.
gammaH J6 Centrifugal distortion of gamma.
gammaL J8 Centrifugal distortion of gamma.
