Necessary items for SSNMR experiments:

    To record spectra from SSNMR 600 and 500 MHz SSNMR, please provide the following: 

  1. Short code for recharge
  2. Sample tube for static samples 
  3. MAS rotor 

        *The tubes and rotors must be approved by Dr. Vivekanandan Subramanian. 
    4.  Liquid Nitrogen or N2 gas for VT experiments 

MAS Rotor (Magic Angle Sample spinning for liquid samples using nanoprobe)

Since the quality of the experiments and data are highly dependent on the sample quality and packing inside the MAS rotor, it is important to purchase quality rotors from a recommended vendor. Please contact Dr. Vivekanandan Subramanian for details about rotor (dimension, material, cap quality, vendor etc.,) or visit www.agilent.com 

SSNMR is not a straight technique that can be readily applied in the same manner to every chemical. For example, following are some of the aspects that need to be considered in detail for a better outcome in a commonly used CPMAS experiment. 

  1. Is the sample crystal, amorphous, semi-solid, or temperature sensitive? 
  2. What is an optimum nrot ? 
  3. What is the T1? 
  4. What nuclei is suitable for detection? 
  5. Is the sample packed well in the rotor? 
  6. What is the optimum temperature? 
  7. What is the optimum 1H decoupler power?
