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 ...

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-

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.

Excited dipole bound electronic states of potassium iodide anions: A theoretical perspective

AIP Advances, 2023
The information about electronic excited states of molecular anions is of pivotal importance for understanding electron attachment/detachment processes. Here, we present a high-level theoretical study on electronic states of potassium iodide anions (KI−).
