molspecutils.molecule.COEffectiveMode

class COEffectiveMode(manifolds, engine_or_path=None, iso=1)

Bases: molspecutils.molecule.COAlchemyMode

__init__(manifolds, engine_or_path=None, iso=1)

Provide transition and energy level data for CO.

Parameters

• engine_or_path – Path to directory with HAPI or sqlite3 database or sqlachemy.Engine instance of opened sqlite3 database.

• iso – Isotopologue number. Required for fetching data and calculating appropriate total partition function.
