    On-line combination of supercritical-fluid chromatography with fast-atom bombardment mass spectrometry (1990)

    Notes: Studies on combined supercritical-fluid chromatography (SFC) using a packed column, with fast-atom bombardment mass spectrometry (FAB-MS) are described. The interfacing was successfully carried out by simply coupling a frit interface between the liquid chromatograph (LC) and the mass spectrometer. The interface was equipped with a pneumatic splitter and post-column addition device delivering FAB matrix material to a release valve which maintained a constant back-pressure at the column outlet. Using a 1% glycerol solution as a matrix compound in the release valve, the SFC/FAB-MS combination operates as well as a normal LC/MS instrument. The performance was demonstrated with a mixture of α-, β- and γ-tocopherol and Triton X-100 (poly(ethylene glycol) p-isooctylphenyl ether).

    Notes: We measured the Fourier transform infrared spectra of brain microsomal membranes prepared from rats fed under two dietary oil conditions with and without brightness-discrimination learning tasks: one group fed α-linolenate deficient oil (safflower oil) and the other group fed the sufficient oil (perilla oil) from mothers to offspring. The infrared spectra of microsomes under the two dietary conditions without the learning task showed no significant difference in the range 1000-3000 cm-1. Only after the learning task were the infrared spectral differences noted between the microsomal membranes from both groups. Spectral differences were observed mainly in the absorption bands of fatty acid ester at around 1730 cm-1 (sn-2 position), those of phosphate and oligosaccharides in the range of 1050-1100 cm-1, and a band at around 1145 cm-1. The infrared band of fatty acid ester at the sn-2 position in the microsomal membrane shifted to a longer wavenumber position in the perilla oil group than in the safflower oil group, suggesting a difference between both groups in hydrogen bonding of the fatty acid ester with water. A band observed at 1055 cm-1 and a small band at around 1145 cm-1 in the second derivative spectrum decreased in intensity in the perilla oil group after learning task. These bands were assigned mainly to the oligosaccharide C - O bond in hydroxyl groups that might interact with some other membrane components. These results suggest changes in hydration of membrane surface and modification in oligosaccharide environment (removal or modification) of microsomes, which may be correlated in part with dietary oil-induced changes in learning performance. © 1997 John Wiley & Sons, Inc.

    Notes: The unusual electronic spectrum of the title compound is shown to be due to the strong interaction between the π-orbitals of the double bonds and the Walsh-orbitals of the fourmembered ring.

    Notes: The bands with Iv 〈 13 eV in the photoelectron spectra of quinoline (IX), isoquinoline (X), cinnoline (XI), quinazoline (XII), and quinoxaline (XIII) have been reassigned in a way consistent with the assignment proposed for pyridine (II), the diazines (III, IV, V), s-triazine (VI), and 1,2,4,5-tetrazine (VII). The bands corresponding to the ejection of an electron from a π-orbital have been identified by a regression calculation based on a HMO perturbation treatment. It has been found that the combined through-space and through-bond interaction of the lone pairs in III, IV, V and in their corresponding benzologues XI, XII, XIII are the same within experimental error ( ±, 0.2 eV). Our assignment is also supported by an empirical correlation of the pKa, 1- values and the mean lone-pair ionization potentials of the azaderivatives I to XIII.
