2D NMR: Overview of Homonuclear Correlation Techniques

750
Homonuclear correlation spectroscopy (COSY) is a powerful technique used in Nuclear Magnetic Resonance (NMR) spectroscopy to study the correlations between nuclei of the same type within a molecule. It provides information about scalar couplings between adjacent nuclei, which helps determine connectivity and structural information. There are several COSY variants, each with its unique strengths and experimental parameters.
COSY90 is the standard two-dimensional (2D) COSY experiment that...

The most common and easiest way to display the relationship between two variables, x and y, is a scatter plot. A scatter plot shows the direction of a relationship between the variables. A clear direction happens when there is either:

2D NMR: Overview of Heteronuclear Correlation Techniques

849
Heteronuclear correlation spectroscopy is an analytical technique that investigates the coupling between different types of nuclei, often a proton and an X-nucleus, such as carbon-13 or nitrogen-15. This method is commonly used in nuclear magnetic resonance (NMR) spectroscopy to gain insights into complex chemical compounds' structural and compositional aspects. A typical heteronuclear correlation spectrum displays X-nucleus chemical shifts on one axis and a proton spectrum on the other...

Area of Science:

  • Acoustics
  • Geophysics
  • Oceanography

Background:

  • Ocean surf noise presents a viable ambient source for acoustic sensing.
  • Cross-correlation of noise recorded on spatially separated sensors can reveal wave propagation characteristics.
  • Backscattering configurations are essential for near-surface geophysical investigations.

Purpose of the Study:

  • To investigate the feasibility of using ambient ocean surf noise for acoustic scatterer localization.
  • To analyze backscattered acoustic waves for geophysical surveying applications.
  • To demonstrate scatterer detection and localization using a simple microphone array.

Main Methods:

  • Recording ambient ocean surf noise using pairs of microphones separated by approximately 2 meters.
  • Cross-correlating the recorded noise signals to identify specific wave arrivals.
  • Analyzing time-difference and scattered wave travel times in backscattering configurations.

Main Results:

  • Distinct arrivals corresponding to time-difference and scattered waves were observed in cross-correlation functions.
  • The study successfully demonstrated the localization of a 20 cm radius Polyvinyl chloride pipe scatterer.
  • The experimental setup confirmed the theoretical prediction that a single microphone pair is sufficient for localization.

Conclusions:

  • Ambient ocean surf noise can be effectively utilized for acoustic sensing and scatterer localization.
  • The backscattering method using cross-correlated noise is a promising technique for near-surface geophysical studies.
  • This approach offers a cost-effective and non-invasive method for characterizing subsurface features.
