You can box-zoom and overlay your own spectrum for comparison.

Search by catalog number, name, formula, CAS registry number.

Look for various available spectra under Documents in the full catalog entry.

IR, MS and NMR spectra are from Wiley spectral databases and the Japanese SDBS database, plus 75,000 experimental 13C and 1H NMR spectra from BioRad-Sadtler.

In addition, there are millions of predicted proton and 13C NMR spectra from ACD Labs.

Search by topic, author, chemical identification terms (names, formulas, Registry Numbers), and chemical structures.

The directory can be searched by registry number, molecular formula, chemical name or synonyms in different languages as well as by physical and chemical characteristics and combinations of those data.

ChemnetBase).

Database of over 500,000 organic, inorganic, and organometallic compounds and natural products, with structures, chemical, spectral, and physical data, and selected literature references.

Spectra files are in.spc format, requiring a special viewer such as ShowSPC.

MSMS and multi-stage MSn spectra were acquired at various collision energies, precursor mz, and isolation widths using Collision-induced dissociation (CID) and Higher-energy collisional dissociation (HCD).

Data are included for observed transitions and energy levels of most of the known chemical elements.

ASD contains data on spectral lines with wavelengths from about 20 pm (picometers) to 60 m (meters).

For many lines, ASD includes radiative transition probabilities.

The energy level data include the ground states and ionization energies for all spectra.

Each covers primarily the microwave region with some data for the radio frequency region.

Rotational spectral lines for 121 diatomic molecules, 55 triatomic molecules, and 91 hydrocarbons have been tabulated.

The isotopic molecular species, assigned quantum numbers, observed frequency, estimated measurement uncertainty, and reference are given for each transition.

Resulting from a critical evaluation of the published literature, the database contains over 22,000 line positions, chemical shifts, doublet splittings, and energy separations of photoelectron and Auger-electron lines.

A highly interactive program allows the user to search by element, line type, line energy, and many other variables.

Users can easily identify unknown measured lines by matching to previous measurements.

It allows for spectrum prediction as well as for searching spectra, structures and other properties.

It features peer-reviewed submission of datasets by users.
