thermo¶
- psi4.driver.qcdb.vib.thermo(vibinfo, T, P, multiplicity, molecular_mass, E0, sigma, rot_const, rotor_type=None)[source]¶
Perform thermochemical analysis from vibrational output.
- Parameters:
E0 (
float
) – Electronic energy [Eh] at well bottom at 0 [K],CURRENT ENERGY
.molecular_mass (
float
) – Mass in [u] of molecule under analysis.multiplicity (
int
) – Spin multiplicity of molecule under analysis.rot_const (
ndarray
) – (3,) rotational constants in [cm^-1] of molecule under analysis.sigma (
int
) – The rotational or external symmetry number determined from the point group.rotor_type (
str
) – The rotor type for rotational stat mech purposes: RT_ATOM, RT_LINEAR, other.T (
float
) – Temperature in [K]. Psi default 298.15. Note that 273.15 is IUPAC STP.P (
float
) – Pressure in [Pa]. Psi default 101325. Note that 100000 is IUPAC STP.
