The molecular geometry and vibrational frequencies of trans-1,2-bis(4-pyridyl)-ethylene ( t-BPE) in the ground state were calculated using density functional theory (DFT) methods with 6–31++G(2d,p) basis set. The optimized geometric bond lengths and bond angles are obtained by DFT employin...
The geometry, frequency and intensity of the vibrational bands of trans 1,2-bis(4-pyridyl)ethylene (which is abbreviated as bpe) were obtained using the density functional theory (DFT) with the BLYP, B3LYP, B3PW91 functionals and 6-311G* basis set. The vibrational spectral data obtained ...
The linear bi-functional ‘spacer’ or ‘rod’ trans-1,2-di-(4-pyridyl)-ethylen (bpe) is a particularly good candidate to produce unique structural motifs with beautiful esthetics and useful functional properties owing to its conjugated system [12]. In current work, bpe is explored as ...
