Carrier-envelope-phase measurement of sub-cycle UV pulses using angular photofragment distributions

open access: yesCommunications Physics, 2022
The carrier-envelope-phase of sub-cycle UV pulses strongly influences the dynamics of quantum systems, but its characterization is not accessible experimentally.

Computation of Opacities for Diatomic Molecules [PDF]

open access: yesInternational Astronomical Union Colloquium, 1994
In this section I briefly describe my efforts to improve the atomic and molecular line data. This work is described in more detail in Kurucz (1992a). In subsequent sections I briefly describe three methods for computing opacity and the models and spectra that result from using them.

Global Warming and Mass Extinctions Associated With Large Igneous Province Volcanism

open access: yesGeophysical Monograph Series, Page 83-102., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Analytical development to determine vibrational energy levels and dissociation energy of diatomic molecules

open access: yesFirePhysChem
This study presents the development of an analytical method for calculating vibrational energy levels and dissociation energy of diatomic molecules by solving the Schrödinger equation (SE) via the Floquet theorem and the resonating averages method (RAM ...

The statistical ensemble of q-deformed hyperbolic modified P\"oschl-Teller potential for certain diatomic molecules through Euler-Maclaurin  approach

open access: yesJournal of Nigerian Society of Physical Sciences
The statistical properties are essentially needed to understand the macroscopic behaviours of atomic molecules, which is a crucial aspect of physics and chemistry research.

CLASSICAL 1D LINEAR MODELS FOR INFRARED ABSORPTION AND ESTIMATES FOR THE VIBRATIONAL AMPLITUDES AND ENERGY OF NaCl IONIC COMPOUND [PDF]

open access: yesQuímica Nova
Sodium chloride, NaCl, was analyzed using two models based in classical physics with the main objective of verifying whether this ionic crystal is active or not to infrared absorption. The results from the first reduced mass linear diatomic model (RMLDM)

Hyperfine structure constants for diatomic molecules

open access: yesJournal of Research of the National Institute of Standards and Technology, 1998
The multiconfiguration valence-bond method (VB) is applied to diatomic molecules using the Hartree-Fock (HF) atomic basis set. The hyperfine constant, Fermi contact term, is computed as a function of the interatomic separation for the X2∏ ground state of 17OH and X1∑ ground state of 107AgH+ molecules.

Species Dynamics and Gene Expression in Algal Polycultures Under Mixotrophic Cultivation in Outdoor Pilot‐Scale Nordic Conditions

open access: yesBiotechnology and Bioengineering, EarlyView.
These results demonstrate that mixotrophic conditions drive both microbial community shifts and metabolic reprogramming, underscoring the importance of cultivation strategy and polyculture selection for targeted applications such as nutrient recovery and bioproduct generation.

Theoretical Spectroscopic Study for Some Diatomic Molecules

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences, 2017
      In this work, four electronic states ( ,   , and   ) of some diatomic molecules (InF and InCl) was studied by TD-DFT with energy represented by the exchange-correlation energy.

Molecular filming: A director's grammar for visualizing chemistry in motion

open access: yesBulletin of the Korean Chemical Society, EarlyView.
Molecular filming names the practice, not just the product, of ultrafast structural science. In deliberate analogy to molecular editing, which rewrites connectivity in space, molecular filming records geometry in time, assembling time‐ordered structural frames into a movie of atomic motion and recasting the field as a grammar of directorial choices ...
