NIST Elemental Physical Measurement Data Index

An index from the NIST Physical Measurement Laboratory provides access to online scientific data organized by chemical element. It simplifies retrieval from databases covering atomic spectroscopy, atomic data, x-ray absorption, and nuclear data. The data is maintained by the National Institute of Standards and Technology and was last updated in July 2022.

Use Cases

• Query atomic spectroscopy data for a specific element to support computational chemistry models.
• Retrieve nuclear data for an element to inform radiation shielding or materials science research.
• Access x-ray absorption data by element for calibration in analytical instrumentation.
• Use the index to locate atomic data for elements to validate theoretical physics simulations.

Strengths

• Curated by the authoritative National Institute of Standards and Technology (NIST).
• Covers multiple specialized domains: atomic spectroscopy, atomic data, x-ray absorption, and nuclear data.
• Data was updated in July 2022, indicating recent maintenance.

Limitations

• Data is accessed via HTML forms and links, not as a structured, downloadable table or file.
• The specific volume of data points (rows) and available attributes (columns) are not documented.
• For some linked databases, users must manually select additional options to retrieve the final data.
