Amplitude-modulated MQMAS experiments:

• Z-filter
  The same pulse program as that defined for XWINNMR 3.5 operating system
• SPAM-echo/antiecho (2D only)
  The only change is the addtion of 3u delay before the two signal storage lines in the pulse program for XWINNMR 3.5 operating system
• MQMAS data processing:
  Shearing the 2D spectrum with AU program xfshear

• z-filter ±3QMAS for I = 3/2, 5/2, and 7/2
• z-filter ±5QMAS for I = 5/2, 7/2, and 9/2
• z-filter ±7QMAS for I = 7/2 and 9/2
• z-filter ±9QMAS for I = 9/2

Phase-modulated MQMAS experiments:

• Multiplex SPAM (2D only)
  The same pulse program as that defined for XWINNMR 3.5 operating system
• The AU program MSM (Multiplex SPAM MQ) remains valid
