HIGH-ACCURACY QUARTIC FORCE FIELD CALCULATIONS FOR THE SPECTROSCOPIC CONSTANTS AND VIBRATIONAL FREQUENCIES OF 11A′ l-C3H−: A POSSIBLE LINK TO LINES OBSERVED IN THE HORSEHEAD NEBULA PHOTODISSOCIATION REGION [PDF]

, 2013
It has been shown that rotational lines observed in the Horsehead nebula photodissociation region (PDR) are probably not caused by l-C3H+, as was originally suggested.

Opacities of S-type Stars: The Singlet B 1Π–X 1Σ+, B 1Π–A 1△, and C 1Σ+–X 1Σ+ Band Systems of ZrO

The Astrophysical Journal, 2023
The ZrO B ^1 Π– X ^1 Σ ^+ , B ^1 Π– A ^1 Δ, and C ^1 Σ ^+ – X ^1 Σ ^+ band systems are important opacity sources in the near-infrared and optical spectra of S-type stars.

(Ro)vibrational Spectroscopic Constants, Lifetime and QTAIM Evaluation of Fullerene Dimers Stability

Molecules, 2023
The iconic caged shape of fullerenes gives rise to a series of unique chemical and physical properties; hence a deeper understanding of the attractive and repulsive forces between two buckyballs can bring detrimental information about the structural ...

Interaction of sulforaphane with DNA and RNA. [PDF]

PLoS ONE, 2015
Sulforaphane (SFN) is an isothiocyanate found in cruciferous vegetables with anti-inflammatory, anti-oxidant and anti-cancer activities. However, the antioxidant and anticancer mechanism of sulforaphane is not well understood. In the present research, we

Determination of spectroscopic constants from rovibrational configuration interaction calculations

, 2022
Rotational constants and centrifugal distortion constants of a molecule are the essence of its rotational or rovibrational spectrum (e.g., from microwave, millimeter wave, and infrared experiments).

Characterization of amorphous carbon films from 5 nm to 200 nm on single-side polished a-plane sapphire substrates by spectroscopic ellipsometry

Frontiers in Physics, 2022
In this work, a series of amorphous carbon films were deposited on a-plane sapphire substrates by magnetron sputtering with deposition time from 15 min to 8 h, in order to investigate the thickness and optical properties in the process of growth in a non-

Optical constants of graphene measured by spectroscopic ellipsometry [PDF]

, 2010
A mechanically exfoliated graphene flake ( ? 150×380??m2) on a silicon wafer with 98 nm silicon dioxide on top was scanned with a spectroscopic ellipsometer with a focused spot ( ? 100×55??m2) at an angle of 55°. The spectroscopic ellipsometric data were

Comparative Extraction of Aluminum Group Metals Using Acetic Acid Derivatives with Three Different-Sized Frameworks for Coordination

Separations, 2021
We prepared acetic acid derivatives using three different frameworks, calix[4]arene, alkenyltrimethylol, and trihydroxytriphenylmethane, which differ in the number and size of their coordination sites.

Performance of W4 theory for spectroscopic constants and electrical properties of small molecules. [PDF]

Journal of Chemical Physics, 2010
Accurate spectroscopic constants and electrical properties of small molecules are determined by means of W4 and post-W4 theories. For a set of 28 first- and second-row diatomic molecules for which very accurate experimental spectroscopic constants are ...
