UV–Vis Spectrum01:30

UV–Vis Spectrum

1.6K
When light passes through a substance, a portion of the light is absorbed while the remaining light is reflected or transmitted. If the molecule absorbs light between the wavelengths of 180–400 nm range, the UV spectrum is obtained, and if it absorbs light in the 400–780 nm wavelength range, the visible spectrum is obtained.     
The UV–Vis spectrum of a molecule is the plot of its absorbance versus wavelength. The plot is drawn by taking molar...

Atomic Emission Spectroscopy: Instrumentation

774
The instrumentation of atomic emission spectrometry (AES) involves various components, including atomization devices that convert samples into gas-phase atoms and ions. There are two main types of atomization devices: continuous and discrete atomizers.  Continuous atomizers, like plasmas and flames, introduce samples in a constant stream, while discrete atomizers inject individual samples using syringes or autosamplers. The most common discrete atomizer is the electrothermal atomizer.

UV–Vis Spectrometers

2.0K
The absorbance of UV and visible (UV–visible) radiations is measured using a UV–visible spectrophotometer. Deuterium lamps, which emit UV radiation, and tungsten lamps, which produce radiation in the visible region, are used as light sources in UV–visible spectrophotometers. A monochromator or prism is used for diffraction grating, i.e., to split the incoming radiation into different wavelengths. A system of slits is used to focus the desired wavelength on the sample cell.

¹H NMR: Interpreting Distorted and Overlapping Signals

1.2K
Spin systems where the difference in chemical shifts of the coupled nuclei is greater than ten times J are called first-order spin systems. These nuclei are weakly coupled, and their chemical shifts and coupling constant can generally be estimated from the well-separated signals in the spectrum.
As Δν decreases and the signals move closer, the doublets appear increasingly distorted. The intensities of the inner lines increase at the cost of those of the outer lines as the signals are...

Atomic Absorption Spectroscopy: Atomization Methods

872
Atomic Absorption Spectroscopy (AAS) atomizes samples through flame atomization or electrothermal atomization. Flame atomization typically involves a nebulizer and spray chamber assembly to combine the sample with a fuel–oxidant mixture, creating a fine aerosol mist that enters a burner. Typically, the fuel and oxidant are combined in an approximately stoichiometric ratio. However, for atoms that are easily oxidized, a fuel-rich mixture may be more advantageous. Only about 5% of the...

IR Spectrum Peak Splitting: Symmetric vs Asymmetric Vibrations

1.4K
Identical bonds within a polyatomic group can stretch symmetrically (in-phase) or asymmetrically (out-of-phase). Similar to hydrogen bonding, these vibrations also influence the shape of the IR peak. Generally, asymmetric stretching frequencies are higher than symmetric stretching frequencies. For example, primary amines exhibit two distinct IR peaks between 3300–3500 cm−1 corresponding to the symmetric and asymmetric N-H stretching, while secondary amines exhibit a single...

Area of Science:

  • Psychology
  • Psychopathology Research
  • Taxonomic Classification Systems

Background:

  • The Hierarchical Taxonomy of Psychopathology (HiTOP) provides an empirically-based classification system for mental health conditions.
  • Detachment is recognized as a key spectrum within the current HiTOP framework.
  • Developing reliable measures is crucial for advancing the HiTOP model and understanding psychopathology.

Purpose of the Study:

  • To create initial scales for the HiTOP Detachment spectrum.
  • To assess facets of Detachment and related constructs for a comprehensive HiTOP measure.
  • To refine measurement tools for psychopathology classification.

Main Methods:

  • Utilized a pool of 247 Detachment items assessing 15 low-order constructs.
  • Employed factor analyses and ant colony optimization for scale development.
  • Collected data from 456 MTurk participants and 266 university students.

Main Results:

  • Developed seven 8-item scales for unipolar Detachment facets: anhedonia, suspiciousness, social withdrawal, intimacy avoidance, unassertiveness, risk aversion, and restricted affectivity.
  • Identified three 8-item scales for Maladaptive Extraversion (attention-seeking, thrill-seeking, domineering).
  • The 10 scales demonstrated unidimensionality, reliability, and initial validity.

Conclusions:

  • The developed scales provide a foundation for a comprehensive HiTOP Detachment measure.
  • Findings highlight the distinctiveness of Maladaptive Extraversion from unipolar Detachment.
  • Further research is needed to address challenges in assessing Detachment for the HiTOP system.
