IR Frequency Region: Fingerprint Region01:03

IR Frequency Region: Fingerprint Region

963
IR spectra are divided into two main regions: the diagnostic region and the fingerprint region. The diagnostic region of the spectrum lies above 1500 cm−1. The absorptions resulting from single-bond vibrations of the N–H, C–H, and O–H stretch at higher wavenumbers and appear on the left side of the spectrum. The stretching absorptions of the C≡C and C≡N occur between 2100–2300 cm−1. In contrast, those arising from stretching absorptions of the...

NMR Spectrometers: Radiofrequency Pulses and Pulse Sequences01:17

NMR Spectrometers: Radiofrequency Pulses and Pulse Sequences

851
A pulse is a short burst of radio waves distributed over a range of frequencies that simultaneously excites all the nuclei in the sample. Upon passing a radio frequency pulse along the x-axis, the nuclei absorb energy corresponding to their Larmor frequencies and achieve resonance. This shifts the net magnetization vector from the z-axis toward the transverse plane. This angle of rotation of the magnetization vector, or the flip angle, is proportional to the duration and intensity of the pulse.

IR Spectrum Peak Splitting: Symmetric vs Asymmetric Vibrations01:08

IR Spectrum Peak Splitting: Symmetric vs Asymmetric Vibrations

1.1K
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...

NMR Spectrometers: Resolution and Error Correction

740
When magnetic nuclei in a sample achieve resonance and undergo relaxation, the signal detected in NMR is an approximately exponential free induction decay. Fourier transform of an exponential decay yields a Lorentzian peak in the frequency domain. Lorentzian peaks in an NMR spectrum are defined by their amplitude, full width at half maximum, and position, where the peak width is governed by the spin-spin relaxation time alone. In real experiments, however, the applied magnetic field is rendered...

The Electromagnetic Spectrum02:37

The Electromagnetic Spectrum

53.1K
The electromagnetic spectrum consists of all the types of electromagnetic radiation arranged according to their frequency and wavelength. Each of the various colors of visible light has specific frequencies and wavelengths associated with them, and you can see that visible light makes up only a small portion of the electromagnetic spectrum. Because the technologies developed to work in various parts of the electromagnetic spectrum are different, for reasons of convenience and historical...

IR Frequency Region: X–H Stretching01:24

IR Frequency Region: X–H Stretching

1.0K
In IR spectroscopy, signals produced by the X−H bonds (such as C−H, O−H, or N−H) can be observed in the frequency range of  2700–4000 cm–1. The C−H stretching vibration forms sharp bands in the region 2850–3000 cm–1. The presence of the O−H stretching vibration leads to the forming of an absorption band in the frequency range 3650–3200 cm−1. At the same time, N−H stretching can be confirmed by absorption bands in...

Area of Science:

  • Neuroscience
  • Cognitive Science
  • Electrophysiology

Background:

  • Individualized measures of electroencephalographic (EEG) activity are gaining prominence.
  • Gamma-band activity (30-100 Hz) is crucial for sensory and cognitive functions.
  • Individual Gamma Frequency (IGF) is recognized for its importance but remains understudied.

Purpose of the Study:

  • To provide a comprehensive overview of the functional properties of peak gamma frequency (IGF).

  • Literature review synthesizing existing research on IGF.
  • Analysis of factors influencing IGF.
  • Discussion of methodological variability in IGF extraction.

Main Results:

  • Individual Gamma Frequency (IGF) appears to be modulated by both internal (endogenous) and external (exogenous) factors.
  • The broad functional roles linked to IGF suggest diverse underlying neural mechanisms.
  • Significant variability exists in reported IGF values (30-100 Hz), potentially due to differing extraction methodologies.

Conclusions:

  • Individual Gamma Frequency (IGF) is influenced by multiple factors, indicating complex functional roles.
  • Further research is essential, employing diverse stimulation techniques and examining multiple functional aspects within the same cohort.
  • Optimization of IGF extraction methods is crucial for reliable and comparable findings across studies.
