Target entity: NMR
Context triple: [Nilgiri Mountain Railway, popularName, NMR]
  • A. NMRCL
    NMRCL is the corporate entity responsible for developing, operating, and maintaining the Nagpur Metro rail system in Nagpur, India.
  • B. Karplus equation for NMR coupling constants
    The Karplus equation for NMR coupling constants is an empirical relationship that links three-bond scalar coupling values between nuclei to the dihedral angle between them, enabling the determination of molecular conformations from NMR data.
  • C. MRI
    MRI (Matz's Ruby Interpreter) is the standard reference implementation of the Ruby programming language, written in C and known for prioritizing simplicity and developer happiness.
  • D. Principles of Magnetic Resonance
    Principles of Magnetic Resonance is a foundational textbook that systematically explains the theory and applications of magnetic resonance phenomena, particularly nuclear magnetic resonance (NMR), for advanced students and researchers in physics and chemistry.
  • E. Bloch–McConnell equations
    The Bloch–McConnell equations are an extension of the Bloch equations that describe nuclear magnetic resonance (NMR) signal evolution in systems with chemical exchange between different spin populations.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
