“…The most remarkable feature continues to be the Z (syn) configuration of the oxygens with respect to the NdN bond, and no evidence has ever been reported for the presence of the E (anti) configuration (even in solution). Analogy to the C-bound structures is not surprising given the fact that all the spectroscopic evidence given above 6 as well as a study of the photoelectron spectra of several O 2 -alkylated N-diazeniumdiolates 205 shows virtually no interaction between the N 2 O 2 functional group and the lone pair of electrons possessed by the nitrogen to which it is attached. Inspection of the literature referenced in this review reveals that no evidence of hindered rotation about the N-N single bond has ever been observed by NMR spectroscopy.…”

“…Specific NMR study of N-bound diazeniumdiolates has been limited to a single report 203 of the 15 N NMR of DEA/NO ( 26 ), which reports chemical shifts of 215 and 386.5 ppm (relative to ammonium chloride reference) for the two nitrogens of the functional group. A limited amount of photoelectron spectroscopy has also been reported (see the next section) …”

Joseph A. Hrabie received his entire education in the New York City public school system, including his Ph.D. degree in Chemistry (1981) under the guidance of Professor William F. Berkowitz at Queens College of the City University of New York. After postdoctoral research with Professor Herbert O. House at the Georgia Institute of Technology, he moved to the National Cancer Institute at Frederick and is currently a Senior Scientist with SAIC−Frederick, the primary NCI contractor at the site. In addition to many scientific publications, his continuing interest in nitric oxide chemistry has resulted in 15 U.S. patents. Larry K. Keefer received his B.A. degree from Oberlin College and his Ph.D. degree in Chemistry (1965) under the guidance of Professor Gloria G. Lyle at the University of New Hampshire. He held research positions at the Chicago Medical School and the University of Nebraska College of Medicine before coming to the National Cancer Institute in 1971. He and his colleagues in the NCI's Chemistry Section, Laboratory of Comparative Carcinogenesis, are intensively studying the chemistry and pharmacology of the diazeniumdiolates as nitric oxide sources for biomedical applications.This section contains a description of reactions that are used preparatively as well as those that do not
