Electric deflection of imidazole dimers and trimers in helium nanodroplets: Dipole moments, structure, and fragmentation [PDF]
Journal of Chemical Physics v.153, 081101 (2020), 2020 Deuterated imidazole (IM) molecules, dimers and trimers formed in liquid helium nanodroplets are studied by the electrostatic beam deflection method. Monitoring the deflection profile of (IM)D+ provides a direct way to establish that it is the primary product of the ionization-induced fragmentation both of (IM)2 and (IM)3.

Raman Scattering Spectra of Boron Imidazolate Frameworks Containing Different Magnetic Ions [PDF]
, 2023 We present a Raman scattering spectroscopic study of boron imidazolate metal-organic frameworks (BIFs) with three different magnetic metal ions and one non-magnetic in a wide frequency range from 25 to 1700 cm$^{-1}$, which covers local vibrations of the linkers and well as collective lattice vibrations. We show that the spectral region above 800 cm$^{-

Characterizing and contrasting structural proton transport mechanisms in azole hydrogen bond networks using ab initio molecular dynamics [PDF]
J. Phys. Chem. Lett. 2021, 12, 36, 8749-8756, 2021 Imidazole and 1,2,3-triazole are promising hydrogen-bonded heterocycles that conduct protons via a structural mechanism and whose derivatives are present in systems ranging from biological proton channels to proton exchange membrane fuel cells. Here, we leverage multiple time-stepping to perform ab initio molecular dynamics of imidazole and 1,2,3 ...

Electron impact partial ionization cross sections: R-carvone, 2-butanol, imidazole, and 2-nitroimidazole [PDF]
, 2023 We theoretically calculate the electron impact partial and total ionization cross sections of R-carvone $(\mathrm{C_{10}H_{14}O})$, 2-butanol $(\mathrm{C_{4}H_{10}O})$, imidazole $(\mathrm{C_3H_4N_2})$ and 2-nitroimidazole $(\mathrm{C_3H_3N_3O_2})$. We have used the Binary Encounter Bethe (BEB) model to obtain the total electron impact ionization cross

Syntheses of polyalkylated imidazoles
Synthetic Communications, 2017 We have developed improved general simple methods for large-scale preparation of polyalkylated imidazoles by improved multicomponent synthesis from commercially available starting materials. A large range of NH- and N-alkyl-polyalkylimidazoles (40 in total, including novel compounds) has been synthesized.
