603: Cryoprobe 5mm TCI-Z, #Z44896_0077

In principle: Do NOT trust these values blindly - verify them if questionable!

Amplifiers can go bad or your sample environment like salt, temperature, ... might alter the pulse width!

1. General Information:

  • Shimfile: chloshim.600 is a good starting point for aqueous samples
  • Read Pulses from Master List:
    • read in pulse sequence and Parameter file
    • Type getprosol or click on the test tube symbol in ased
    • For proton pulses type: getprosol 1H , where p1 is the determined pulse length [us] at the power level pl1 [dB].
