Notes: Electroblotting proteins separated by gel electrophoresis provides a suitable support for further manipulations and analysis of small amounts of relatively pure samples. On-membrane digestion, peptide mapping by mass spectrometry, and database searching offer sensitive and fast tools to identify the analyte. By providing sequence information, tandem mass spectrometry can go a step further, confirming the database identification, solving problems connected with post-translational modifications and sequence variations, or supplying the stretches of internal sequence necessary to synthesize an oligonucleotide probe for gene isolation. The viability of this approach was successfully evaluated using different tandem mass spectrometric techniques: metastable decomposition in a matrix-assisted laser desorption/ionization (MALDI) time-of-flight instrument with a curved-field reflectron; low energy collision-induced dissociation in a MALDI quadrupole ion trap mass spectrometer; and high energy collision-induced dissociation in a high-performance four-sector mass spectrometer with massive cluster-impact ionization.

Notes: Two different mass spectrometric techniques have been used to analyse the products resulting from Curie-point pyrolysis of nucleic acids: low voltage ionization quadrupole mass spectrometry and high resolution field ionization mass spectrometry. The spectra obtained with both techniques are in good agreement with one another. As already indicated by the low resolution spectra, the high resolution spectra proved that most of the peaks originate from the carbohydrate moiety of the nucleic acid. Micrograms of DNA/RNA can be distinguished very easily by use of these key fragments, although the bases themselves are not found. Some significant pyrolysis mechanisms are proposed.

Notes: It is shown by deuterium-labelling experiments, that a substantial part of the [M - CH2OH]+-ions from 2-methyl-2-phenyl-propane-1,3-diol must have rearranged to carbonyl-oxygen protonated phenylacetone by a positional interchange of the phenyl- and hydroxyl groups prior to decomposition.

Notes: We detected and studied CIDNP effects in the reaction of substituted benzyl chlorides with n-butyllithium in hexane (Scheme 1) in various magnetic fields (from 0·5 Oe to about 25,000 Oe). The polarisation of 19F nuclei in the reaction of p-F-benzyl chloride in strong fields has been observed by Rakshys.1 We succeeded, however, in finding the CIDNP effects for both 19F and 1H in all the reactions investigated. The CIDNP effects observed offer a number of remarkable features; therefore, a detailed analysis of these effects can be useful for a better understanding of the nature of CIDNP.

Notes: Three bicyclic thioketones were examined by combined gas chromatography-mass spectrometry. Deuterium labelling was employed in the interpretation of the fragmentation processes in thiocamphor. Compared with the oxygen analogues, the thiones yielded on electron-impact a higher proportion of characteristic fragment ions containing the hetero-atom.

Notes: The effect of the magnetic field on CIDNP can be found in many chemical reactions. It is considered to result from the fact that the probability of singlet-triplet transitions in a radical pair is determined by magnetic interactions in the pair and is field strength dependent. In the present communication we wish to demonstrate that for the same reason the external magnetic field can also markedly affect the rates of chemical reactions involving free radicals.
