    Time course of cigarette widhdrawal symptoms while using nicotine gum (1989)
    Springer
    Psychopharmacology 99 (1989), S. 143-145 
    Details
    ISSN: 1432-2072
    Keywords: Smoking ; Withdrawal symptoms ; Timecourse ; Nicotine gum
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract Ratings of withdrawal symptoms were provided at weekly intervals by 147 smokers clinic clients who managed complete abstinence for 4 weeks. The ratings followed a similar temporal pattern regardless of amount of nicotine gum used. Irritability, depression, difficulty concentrating and restlessness peaked in the 1 st week or two and returned to baseline by week 4. Hunger was more persistent. Craving was reported to be the most troublesome withdrawal symptom at first, although by the 4th week hunger was cited almost as often. Across all subjects,e venings were cited most often as the worst time of day for craving but among heavier smokers and those who used more nicotine gum mornings were considered worst.

    29Si nuclear magnetic resonance of dimethyl and phenylmethyl containing polysilanes (1988)
    Bognor Regis [u.a.] : Wiley-Blackwell
    Journal of Polymer Science Part A: Polymer Chemistry 26 (1988), S. 701-712 
    Details
    ISSN: 0887-624X
    Keywords: Chemistry ; Polymer and Materials Science

    Topics: Chemistry and Pharmacology
    Notes: The 29Si-NMR spectra are reported for poly(methylphenylsilylene), 1, poly(1,1,2-trimethyl-2-phenyldisilene) 2, two samples of poly(dimethylsilylene-co-phenylmethylsilylene), 3a and 3b, and poly(phenylmethylsilylene-co-n-hexylmethylsilylene), 4. The spectra of 3a, 3b, and 4 indicate that these polymers contain blocklike regions with considerable segregation of RMeSi and PhMeSi groups. The spectrum of 2 shows no evidence for stereospecific polymerization. The preparation of 2 from 1,1,2-trimethyl-2-phenyldichlorosilane is also described.

    29Si nuclear magnetic resonance of dialkylpolysilanes (1988)
    Bognor Regis [u.a.] : Wiley-Blackwell
    Journal of Polymer Science Part A: Polymer Chemistry 26 (1988), S. 713-720 
    Details
    ISSN: 0887-624X
    Keywords: Chemistry ; Polymer and Materials Science

    Topics: Chemistry and Pharmacology
    Notes: The silicon-29 nuclear magnetic resonance spectra of a number of dialky- and alkylmethylpoly-silanes are reported. Polysilanes composed of asymmetrically substituted silylenes (i.e., alkylmethylsilylenes) exhibited very broad resonance lines attributed to diastereomeric chemical shifts of stereogenic silylenes alpha and beta to the observed nucles Symmetrically substituted polysilanes showed a single narrow peak. The 29Si chemical shifts for these polysilanes decrease with increasing steric bulk of the substituents, varying inversely with the electronic excitation energy.
