I have a question about 31P EXSY, you made it just from simple gradient 1H-1H noesy pulse sequence by the changing of nucleus? Is it the same like with 1H-X HMQC, where you can take simple carbon HMQC pulse sequence, change nucleus and recalculate gradients for the new nucleus?<br /><br />Best regards, <br />RomanAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-3300702123878659843.post-8861791195688305292013-03-20T08:40:40.582-04:002013-03-20T08:40:40.582-04:00Vowa,
Find below the answers to your questions.
...Vowa,<br /><br />Find below the answers to your questions.<br /><br />1. The "bg" stands for background suppression. See http://u-of-o-nmr-facility.blogspot.ca/2010/04/background-suppression-in-liquids.html<br /><br />2. The EXSY buttons sets up gradient NOESY sequences. In the case of 31P EXSY proton decoupling is used as well.<br /><br />3. The HALT button starts a macro the issues the standard Bruker HALT command as well as print a message. It does not respect any phase cycling. It does not use the STOP command.<br /><br />4. The "tips" switch turns on the feature that a short description of a button appears on the screen while the mouse cursor hovers over the button.<br /><br />GlennGlenn Faceyhttps://www.blogger.com/profile/05146575170575279335noreply@blogger.comtag:blogger.com,1999:blog-3300702123878659843.post-16626084103888480162013-03-19T17:55:43.629-04:002013-03-19T17:55:43.629-04:00Dear Glen,

If you press HALT in DEPT kind of experiments does the au program just execute "halt" (the number of scans is set as NS) or it does "stop" (the number of scans is finitely set by TD0)?<br />4. What is "Tips" (above)?<br /><br />Thank you in advance!<br /><br />VowaAnonymousnoreply@blogger.com
