JSON schema for input

JSON schema for simplified Molpro input

https://www.molpro.net/schema/molpro_input.json
Structured input for Molpro that covers the case of a single ansatz, with a given basis set at a given geometry. All fields are optional, with reasonable defaults, although at least geometry, method and basis will normally be specified
type	object
properties
geometry	The geometry, in any form that Molpro will accept. If the value is the name of a readable file, that file will be the source of the geometry specification; otherwise, the value will be interpreted directly, with or without enclosing {}.

	default	He
job_type	The job type - single point, optimisation, frequencies etc.
	default	SP
	anyOf	Single point
		Calculate at a single geometry
		default
		const	SP
		Geometry optimisation
		Optimise the geometry
		const	OPT
		Hessian
		Calculate harmonic force constants and normal modes
		const	FREQ
		Optimise + vib frequencies
		Optimise the geometry and then calculate normal modes
