Infrared (IR) Spectroscopy: Overview01:09

Infrared (IR) Spectroscopy: Overview

1.8K
When electromagnetic radiation passes through a material, atoms or molecules transition from a lower to a higher energy state by absorbing radiation corresponding to the energy difference between the two states. The absorption of infrared (IR) radiation causes transitions between vibrational energy levels in a molecule. Therefore, IR spectroscopy is a useful analytical tool for determining the molecular structure of molecules.
Different compounds display unique properties due to their...

IR Spectroscopy: Molecular Vibration Overview

2.3K
When Infrared (IR) radiation passes through a covalently bonded molecule, the bonds transition from lower to higher vibrational levels. The fundamental vibrational motions that result in infrared absorption can be classified as stretching or bending vibrations.
Stretching vibrations are vibrational motions that occur along the bond line, changing the bond length or distance between two bonded atoms. They are further distinguished as symmetric or asymmetric. In symmetric stretching, the...

Attenuated Total Reflectance (ATR) Infrared Spectroscopy: Overview01:13

Attenuated Total Reflectance (ATR) Infrared Spectroscopy: Overview

371
Attenuated total reflectance (ATR) infrared spectroscopy is a powerful analytical technique used to study the composition of materials. It is widely employed in chemistry, materials science, forensic science, and other fields where sample characterization is required. ATR has several advantages over traditional transmission IR spectroscopy, including the requirement of little to no sample preparation and the ability to analyze a wide range of samples.
The ATR process begins by directing a beam...

IR Spectroscopy: Hooke's Law Approximation of Molecular Vibration01:16

IR Spectroscopy: Hooke's Law Approximation of Molecular Vibration

1.3K
A covalently bonded heteronuclear diatomic molecule can be modeled as two vibrating masses connected by a spring. The vibrational frequency of the bond can be expressed using an equation derived from Hooke's law, which describes how the force applied to stretch or compress a spring is proportional to the displacement of the spring. In this case, the atoms behave like masses, and the bond acts like a spring.
According to Hooke's law, the vibrational frequency is directly proportional to...

Ultraviolet and Visible (UV–Vis) Spectroscopy: Overview01:02

Ultraviolet and Visible (UV–Vis) Spectroscopy: Overview

2.6K
Ultraviolet–visible (UV–visible or UV–Vis) spectroscopy is an analytical technique that investigates the interaction between matter and UV–Vis light within the electromagnetic spectrum. This method is widely used for its versatility, simplicity, and relatively quick data acquisition, making it valuable for both qualitative and quantitative analysis. When UV–Vis radiation passes through a material,  molecules absorb light depending on the energy required for...

Area of Science:

  • Biomedical Engineering
  • Neonatal Physiology
  • Medical Monitoring

Background:

  • Premature infants face risks of hypoperfusion affecting vital organs.
  • Current monitoring methods may not detect subtle, early changes in tissue perfusion.
  • Early detection of perfusion alterations is crucial for timely clinical intervention.

Purpose of the Study:

  • To evaluate Near-infrared spectroscopy (NIRS) as an adjunct for monitoring neonatal tissue oxygen extraction.
  • To highlight NIRS's capability in detecting early, localized perfusion changes in neonates.
  • To support the clinical utility of NIRS in managing conditions associated with hypoperfusion in premature infants.

Main Methods:

  • Utilized Near-infrared spectroscopy (NIRS) for continuous, real-time measurement of regional oxygen extraction.
  • Applied NIRS noninvasively at the bedside in neonatal research settings.
  • Focused on assessing cerebral, intestinal, and kidney tissue beds.

Main Results:

  • NIRS demonstrated effectiveness as a surrogate marker for end-organ perfusion.
  • The technology successfully detected minute changes in tissue oxygenation.
