UVVis

class specatalog.models.measurements.UVVis(**kwargs)[source]

UVvis measurement.

This subclass of Measurement represents an UVvis experiment. This model adds the UVvis-specific parameter dim_cuvette.

The model participates in SQLAlchemy polymorphism using the "uvvis" polymorphic_identity. Any row in measurements where method='uvvis' is therefore automatically loaded as a UVVis instance.

id

Primary key linked to measurements.id with cascading delete.

Type:: int

dim_cuvette

Dimension of the cuvette.

Type:: str

Notes

The tablename is uvvis.
All shared measurement metadata (temperature, solvent, operator, timestamps, file path, etc.) are inherited from Measurement.
The id corresponds directly to the entry in the main measurements table via single-table inheritance.

Examples

Creating an UVvis measurement:

>>> from measurements import UVVis
>>> from molecules import Molecule
>>> mol = Molecule(name="PDI-TEMPO")
>>> m = UVVis(
...     molecule=mol,
...     method="uvvis",
...     temperature=298,
...     solvent="Toluene",
...     date=date(2025, 4, 12),
...     measured_by="Bob",
...     path="/data/M21/measurement_M21.h5",
...     corrected=False,
...     evaluated=False,
...     dim_cuvette = "1cm"
... )
>>> session.add(m)
>>> session.commit()

Loading via polymorphism:

>>> m = session.query(Measurement).filter_by(id=21).one()
>>> type(m)
<class 'models.UVVis'>
