    The laboratory generation of potentially interstellar cumulenes S(Cn)S (n = 2-6) and their radical cations (1990)
    Weinheim : Wiley-Blackwell
    Berichte der deutschen chemischen Gesellschaft 123 (1990), S. 2069-2071 
    Details
    ISSN: 0009-2940
    Schlagwort(e): Interstellar chemistry ; Polycarbon disulfides ; Neutralization-reionization mass spectrometry ; Beam experiments ; Chemistry ; Inorganic Chemistry
    Quelle: Wiley InterScience Backfile Collection 1832-2000
    Thema: Chemie und Pharmazie
    Notizen: The title compounds are generated and characterized in the gas phase by tandem mass spectrometry (neutralization-reionization mass spectrometry); it is demonstrated that both even and odd-numbered polycarbon disulfides S(Cn)S(n = 2-6) are stable species. The elusiveness of the even-numbered analogues (n = 2, 4, 6) in the condensed phase must be due to facile intermolecular reactions.

    On the Generation of Polycarbon Nitride Radicals CnN. (n = 2-5) by Neutralization-Reionization Mass Spectrometry (1991)
    Weinheim : Wiley-Blackwell
    Berichte der deutschen chemischen Gesellschaft 124 (1991), S. 1481-1483 
    Details
    ISSN: 0009-2940
    Schlagwort(e): Interstellar chemistry ; Polycarbon nitride radicals ; Neutralization-reionization mass spectrometry ; Tandem mass spectrometry ; Chemistry ; Inorganic Chemistry
    Quelle: Wiley InterScience Backfile Collection 1832-2000
    Thema: Chemie und Pharmazie
    Notizen: The title radicals, thought to be of prime importance in the genesis of interstellar organic molecules, are accessible in the gas phase by neutralization of the corresponding CnN+ ions (n = 2-5) using tandem mass spectrometry methods (neutralization-reionization mass spectrometry). Collision-induced dissociation reactions of mass-selected CnN+ are in keeping with the connectivity of a “carbon rod” bearing a nitrogen atom at one terminus.

    A Mass-Spectrometric Investigation of CxNO2 (x=1, 2) Ions and Neutrals (1992)
    Weinheim : Wiley-Blackwell
    Berichte der deutschen chemischen Gesellschaft 125 (1992), S. 279-283 
    Details
    ISSN: 0009-2940
    Schlagwort(e): Interstellar chemistry ; Heterocumulenes ; Neutralization-reionization mass spectrometry ; Chemistry ; Inorganic Chemistry
    Quelle: Wiley InterScience Backfile Collection 1832-2000
    Thema: Chemie und Pharmazie
    Notizen: The isomeric [C2,N,O2]+ ions OCNCO+, OCCNO+, and NCCO2- have been generated and structurally characterized on the basis of their collisional activation, charge reversal, and neutralization-reionization mass spectra. The open-shell neutrals formed in the neutralization step undergo facile unimolecular decomposition. A recovery signal is obtained only for OCCNO.

    Mass-spectrometric characterization of isomeric NNCCN and NCNCN Ions and neutrals (1992)
    Weinheim : Wiley-Blackwell
    Berichte der deutschen chemischen Gesellschaft 125 (1992), S. 1517-1520 
    Details
    ISSN: 0009-2940
    Schlagwort(e): Interstellar chemistry ; Heterocumulenes ; Charge-reversal mass spectrometry ; Neutralization-reionization mass spectrometry ; Collisional activation ; Chemistry ; Inorganic Chemistry
    Quelle: Wiley InterScience Backfile Collection 1832-2000
    Thema: Chemie und Pharmazie
    Notizen: Neutralization-reionization mass spectrometry as well as charge reversal and collisional activation experiments serve to distinguish and assign the connectivities NNCCN and NCNCN to isomeric pairs of anions, neutral radicals and cations of C2N3. Loss of N2 to generate C2N+ is the critical discriminant, and the assignment is further substantiated by subjecting these fragment ions to collisional activation experiments by using tandem-mass spectrometry facilities.

    CCS and S(C4)S: The laboratory generation of interstellar molecules and their radical cations (1989)
    Weinheim : Wiley-Blackwell
    Berichte der deutschen chemischen Gesellschaft 122 (1989), S. 1803-1805 
    Details
    ISSN: 0009-2940
    Schlagwort(e): Beam experiments ; Interstellar chemistry ; Dicarbon sulfide ; Butatrienedithione ; Neutralization-reionization mass spectrometry ; Chemistry ; Inorganic Chemistry

    Thema: Chemie und Pharmazie
    Notizen: The title compounds are generated and characterized in the gas phase by mass spectrometric methods (neutralization-reionization mass spectrometry), and for dicarbon sulfide the experimental results are supported by ab initio MO calculations (HF/6-31G*).
