◆ GasTransportData()

GasTransportData	(	const std::string &	geometry,
		double	diameter,
		double	well_depth,
		double	dipole = `0.0`,
		double	polarizability = `0.0`,
		double	rot_relax = `0.0`,
		double	acentric = `0.0`,
		double	dispersion = `0.0`,
		double	quad_polar = `0.0`
	)

Construct a GasTransportData object using MKS units for all parameters.

◆ setCustomaryUnits()

void setCustomaryUnits	(	const std::string &	geometry,
		double	diameter,
		double	well_depth,
		double	dipole = `0.0`,
		double	polarizability = `0.0`,
		double	rot_relax = `0.0`,
		double	acentric = `0.0`,
		double	dispersion = `0.0`,
		double	quad_polar = `0.0`
	)

Set the parameters using "customary" units: diameter in Angstroms, well depth in Kelvin, dipole in Debye, and polarizability in Angstroms^3.

These are the units used in in CK-style input files.
