| Description |
The Units keyword controls the units used in the Z-matrix for distances and angles and related values, such as step-sizes in numerical differentiation. The defaults are Angstroms and degrees.
| Options |
Ang
Distances are in Angstroms (this is the default).
AU
Distances are in atomic units (Bohrs).
Deg
Angles are in degrees (the default).
Rad
Angles are in radians.
| Restrictions |
The Charge, Cube and Massage keywords are not affected by the setting of the Units keyword, and their input is always interpreted in units of Angstroms and degrees.
