    Conventional and Unconventional Intramolecular Hydrogen Bonding in some Beta-diketones 

    Type: Journal Paper
    Author : وحیدرضا داروگر; محمد وکیلی; R. Afzali; سیدفرامرز طیاری; Vahidreza Darugar; Mohamad Vakili; Sayyed Faramarz Tayyari
    Year: 2017
    Abstract:

    This study presents our view of unconventional and conventional intramolecular hydrogen bonds (HBs) for some beta-diketones

    theoretically and experimentally. According to our results, the groups such as phenyl and ...

    Normal coordinate analysis, hydrogen bonding, and conformation analysis of heptane-3,5-dione 

    Type: Journal Paper
    Author : سمیرا سلطانی قوشخانه; محمد وکیلی; سیدفرامرز طیاری; Ali Reza Berenji; Samira Soltani Ghoshkhaneh; Mohamad Vakili; Sayyed Faramarz Tayyari
    Year: 2016
    Abstract:

    Fourier transform Raman and infrared spectral measurements have been made for the heptane-3,5-

    dione (HPD) and simultaneously compared with those of acetylacetone (AA) to give a clear understanding of substitution ...

    Isomerism and Hydrogen Bonding in the Cis-enol Forms of 1-(n-pyridyl)butane-1,3-diones: A Theoretical Study 

    Type: Journal Paper
    Author : راهله افضلی; محمد وکیلی; سیدفرامرز طیاری; حسین عشقی; Raheleh Afzali; Mohamad Vakili; Sayyed Faramarz Tayyari; Hossein Eshghi
    Year: 2016
    Abstract:

    Molecular structure, isomerism, conformational stability and intramolecular hydrogen bonding (IHB) of cis-enol forms of 1-(n-pyridyl)butane-1,3-diones (nPBD) (n = 2, 3, or 4) have been investigated by means of density ...

    Conformational analysis, intramolecular hydrogen bonding, and vibrational assignment of 4,4-dimethyl-1-phenylpentane-1,3-dione 

    Type: Journal Paper
    Author : راهله افضلی; محمد وکیلی; سیدفرامرز طیاری; حسین عشقی; A.-R. Nekoei; Raheleh Afzali; Mohamad Vakili; Sayyed Faramarz Tayyari; Hossein Eshghi
    Year: 2014
    Abstract:

    Abstract

    Molecular structure, conformational stabilities, and intramolecular hydrogen bonding (IHB) of 4,4-dimethyl-1-phenylpentane-1,3-dione (DMPD), have been investigated by means of density functional theory (DFT) ...
