Vibrational spectroscopy

, 2020
In this chapter, starting from the basic concepts of vibrational spectroscopy, we discuss the potential and limitations of IR and Raman techniques applied to nanoparticles. We describe the experimental setups and the sample preparation procedures, discussing also the metrological aspects.

Investigating the Low‐Temperature Phase Stability of the Binary Ta–W System

Advanced Engineering Materials, EarlyView.
Atomistic simulations show that the binary Ta–W system forms ordered intermetallic phases, B2‐TaW and D03‐TaW3, as 0 K ground states. Configurational entropy, however, lowers the free energy of the disordered bcc solid solution, which becomes the stable phase above about 400 K.

Cryogenic Deformation Behavior of TiAl and Insights Into Embrittlement After High‐Temperature Exposure Combined With Secondary Ion Mass Spectroscopy of Near Surface Chemistry

Advanced Engineering Materials, EarlyView.
Near‐surface deuterium enrichment profiles for different microstructural types of TiAl after exposure at 700 °C in a heavy water‐containing environment. The deuterium levels are significantly higher than expected from natural occurrence, indicating that the heavy water dissociated during the exposure treatment and entered the specimens.

Advanced vibrational spectroscopy of magnetite nanoparticles [PDF]

EPJ Web of Conferences
In this work, we discuss the challenges associated with measuring and interpreting the vibrational properties of nanomaterials at mid- and far-infrared frequencies, where vibrational bands are often broad and overlapping.

Spectroscopy learning: A machine learning method for study diatomic vibrational spectra including dissociation behavior

MethodsX, 2020
Molecular spectroscopy plays an important role in the study of physical and chemical phenomena at the atomic level. However, it is difficult to acquire accurate vibrational spectra directly in theory and experiment, especially these vibrational levels ...

THE LOCAL VIBRATIONAL MODE THEORY: AN EFFICIENT ANALYSIS TOOL FOR THE VIBRATIONAL SPECTROSCOPY COMMUNITY [PDF]

, 2023
The local vibrational mode theory originally introduced by Konkoli and Cremer has become over the past years a versatile tool for extracting important chemical information, hidden in vibrational spectroscopy data caused by the delocalized nature of ...

The Role of Ultra‐Thin Passive Films and Organic Adsorbates on Aluminum Chips for a Friction‐Induced Solid‐State Recycling Process

Advanced Engineering Materials, EarlyView.
Despite benefits to storage stability and handleability of aluminum scrap, octadecyl phosphonic acid (ODPA) SAMs reduce the tensile strength of wires produced using friction‐induced recycling. Etching and methyl diphosphonic acid (MDPA) coatings, however, have little effect.

Vibrational Microspectroscopy for Cancer Screening

Applied Sciences, 2015
Vibrational spectroscopy analyses vibrations within a molecule and can be used to characterise a molecular structure. Raman spectroscopy is one of the vibrational spectroscopic techniques, in which incident radiation is used to induce vibrations in the ...
