Ultrafast two-dimensional infrared (2D-IR) vibrational echo spectroscopy can probe the fast structural evolution of molecular systems under thermal equilibrium conditions. Structural dynamics are tracked by observing the time evolution of the 2D-IR spectrum, which is caused by frequency fluctuations of vibrational mode(s) excited during the experiment. However, there are a variety of effects th...

In the current investigation, an attempt is made to synthesize and characterize Citrullus colocynthis stem extract loaded Zinc Oxide Nano Particles (ZnONP-Cc) evaluate cytotoxicity antimicrobial activities of same. The synthesis ZnONP-Cc was carried out characterization in terms UV-Spectrum, Fourier Transform Infra-Red (FT-IR) spectrum, Transmission Electron Microscope (TEM), X-Ray Diffraction ...

Self-association of alcohols; including ethanol, methanol, cyclopentanol and octanol in separate mixtures with inert solvents have been studied using FT-IR spectroscopy. Except for the band at 3640 cm–1 in the IR spectrum of the alcohols which is due to the monomer species, the presence of other bands in the region of stretching vibrational frequencies of OH (3100-3700 cm–1) are attributed to t...

Let (X, T ) be a topological dynamical system and let Φ : X → R be a continuous function on the product space X = X × · · · × X (r ≥ 1). We are interested in the limit of V-statistics taking Φ as kernel: lim n→∞ n ∑ 1≤i1,··· ,ir≤n Φ(T i1 x, · · · , T ir x). The multifractal spectrum of topological entropy of the above limit is expressed by a variational principle when the system satisfies the s...
