Spectroscopy Unknown Data Sets

This is a set of spectroscopic data for the identification of unknown compounds. It was prepared for Chemistry 465, Advanced Spectroscopy, at Widener University by S.E. Van Bramer. Use of this data will require several helper applications. Experimental Details are given below.

Experimental Details

Elemental Composition

The elemental composition for each sample was calculated from the molecular formula of the sample.

Mass Spectrometry

Mass spectra were aquired on the Widener University Finnigan 4000 quadrupole mass spectrometer with 70 eV electron ionization. Samples were introduced through the GC, Injector 250 oC, Oven 200 oC, Transfer line 250 oC. Methylene Chloride was used to rinse the syringe between samples (methylene chloride signal is observed in some of the data).

Mass Spectra were saved as peak tables and formated as jcamp (*.jdx) files that may be viewed using a JCAMP viewer.

NMR

NMR were aquired using the Widener University QE 300+ FT-NMR. Unless noted all spectra were aquired using CDCl3 with 0.2% TMS for the solvent. FID's were downloaded from the spectrometer and converted into NUTS format. The FID's may be processed using NUTS from Acorn NMR. A demo version is available for processing (but not printing or saving) data.
