602: 5mm CPQCI 1H-31P/13C/15N/D Z-GRD (Apr 2011) #Z122656/0001


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
    • Use the getprosol command or click on the test tube symbol in ased
    • For Bruker Pulse Sequences type: getprosol 1H 'p1' ' pldb1' , where p1 is the determined pulse length [us] at the power level pldb1 [dB].
