The SiNMR spectral collection contains 2,325 SiNMR spectra and chemical structures. Most of the chemical shifts are explicitly assigned to the corresponding silicon atoms in the structure. This is the basis of a SiNMR spectrum prediction tool. In addition to structural formula and spectrum, the following information is available: Chemical name Molecular formula Molecular weight Literature reference Solvent Standard Measurement condition The SpecData version of the product is only available in JCAMP format
