SQDTLithium
- class rydstate.species.lithium.SQDTLithium[source]
- Parameters:
args (object)
kwargs (object)
- Return type:
CachedT
- species: ClassVar[str] = 'Li'
The short name of the atomic species.
- is_default: ClassVar[bool] = True
Whether this SQDT is the default SQDT for the species.
- nist_data_file: ClassVar[str | None] = 'nist_data.txt'
Name of the file (in the species directory) with the low-lying NIST energy levels, usually
"nist_data.txt". Left as None for species without a NIST data file.
- ionization_energy: ClassVar[tuple[float, str]] = (43487.1594, '1/cm')
(value, unit).
- Type:
