    Description / Table of Contents: Riassunto Sono state allestite le schede palinologiche diArtemisia vulgaris L.,Artemisia verlotorum Lamotte eArtemisia annua L. su polline fresco e acetolizzato. Le tre specie hanno interesse aerobiologico e allergologico. Vengono anche riportati dati sulla loro distribuzione in Italia, con particolare riferimento adArtemisia annua.
    Notes: Summary Palynological cards ofArtemisia vulgaris L.,Artemisia verlotorum Lamotte and ofArtemisia annua L. are presented for fresh and acetolyzed pollens. The three species have both aerobiological and allergological interest. Data on distribution in Italy are related, with particular attention toArtemisia annua.

    Indirect 1H—19F—1H and 1H—19F—13C nuclear overhauser enhancements: Anomalous intensity effects and applications in conformational analysis (1987)
    Chichester : Wiley-Blackwell

    Notes: Indirect nuclear Overhauser enhancements through 19F have been determined for the three-spin systems 1H-19F-1H and 1H-19F-13C by steady-state presaturation of the appropriate proton, and applied to the conformational analysis of 5-bromo-2-fluoro-4-nitroacetanilide. The 1H NOE difference spectra at 400 MHz showed antiphase doublets for protons undergoing simultaneous dipolar relaxation with, and scalar coupling to, 19F. Similarly, in the 13C selective NOE difference spectrum at 100 MHz, the two lines of the fluorine-bearing carbon showed negative enhancement factors of different magnitude on presaturation of the appropriate proton. The use of these anomalous intensity effects in conformational analysis is illustrated.
