The valid strong THz absorption at 1.58 THz was probed in the organic-inorganic hybrid perovskite thin film, CH3NH3PbI3, fabricated by sequential vacuum evaporation method. In usual solution-based methods such as 2-step solution and antisolvent, we ob
The IR lines for the CH-stretching σu fundamental at 3305cm1 and CH-bending πu fundamental at 625cm1 for C2nH2 (n=5–7) in CCl4 were red-shifted by 220 and 15cm1, respectively, for its complex of C2nH2I6. A few lines were intensified in the low-frequency region of 850–1450...
The spectra closely parallel the spectra of cis lactams except that two combination modes involving the carbonyl stretching fundamental, [ν(NH) + ν(C O)] and [2ν(C =O) + imide III], occur at higher wavenumbers in the imide spectra, reflecting the higher frequency at which this ...
vibrational states/ infrared depletion spectroscopyaniline-toluene clusterThe infrared spectra of the NH 2 stretching vibrations of aniline–toluene cluster and corresponding cluster cation have been measured by the infrared depletion method. The NH 2 stretching vibrations of aniline–toluene cluster were ...
The IR depletion spectrum shows that the OH stretching vibration (3296 cm 1) is red-shifted by 362 cm 1 from that of the bare molecule. The large red-shift in OH frequency, combined with MP2 calculation, reveals that the structure of the cluster is the one with the nitrogen atom of ...
Using an empirical correlation between the NN-distance and the fundamental NH-stretching frequency, the time-dependence of this energy gap along the trajectory is obtained. From the gap-correlation function we determine the infrared absorption spectrum using lineshape theory in combination with a multi...
The structures of the novel heterocyclic compounds were confirmed via 1H-, 13C-, 15N-, and 19F-NMR spectroscopy, as well as HRMS investigations. Keywords: azetidine; oxetane; heterocyclic amines; heterocyclic amino acids; aza-Michael addition; Suzuki–Miyaura cross-coupling reaction Graphical ...
