Chemistry-Chemical Information: Spectra

A free database that explores chemical structure and more

A unique way to search many handbooks and other science and engineering resources.

May select by wavelengths and energy levels

Includes Gas Phase IR, Mass Spectra, UV/Vis spectra, Vibrational and electronic spectra. Searchable by name, CAS RN and some property info.

Provides Magnetic Resonance-related information

Open Access database supported by the National Library of Medicine.

Search by substance and display the chemical's record. There you will find various spectra which can be displayed or references where spectra information can be found. Not available for all compounds but content is growing.

Includes pdfs of many spectra

SDBS Spectral Database

Provides library of spectroscopy problems for practice

Descriptions and links to freeware and commercial software supporting NMR data
