We are increasing security on NMR spectrometers and data stations and plan to move to IUB only IP addresses. You would still be able to access your data outside IUB with VPN. Please contact Doug or Frank if this would pose any problems for your continued enjoyment of the NMR facilities!

Doug and Frank will be attending 53rd Experimental NMR Conference at Miami, FL from April 14th to 20th. Doug will also attend Agilent Users’ Meeting. If you need assistance during this period, contact Dejian (855-4478, Simon 037).

The Chemistry NMR facility is scheduled for the network upgrade starting end of April. We will minimize downtime but there might be some.

HMQC, HSQC and HMBC experiments now work well on the I500 after an unstable broadband RF amplifier was replaced. We have optimized two HSQC experiments for the I500: ”iuhsqc” gives higher sensitivity, “iuhsqcad” gives better quality (less artifacts).

All the spectrometers are operational after the power outage this morning.

HMQC, HSQC and HMBC experiments currently are not working well on the I500 due to a hardware problem. All other experiments, including routine 1H, 13C, COSY, NOESY, ROESY, etc. work with no problem.

No lab gloves are allowed in the NMR facility.

Only capped or sealed tubes are allowed in the NMR facility. All other chemistry (titrations, etc.) must be done elsewhere. A small wet lab (237A) is available off the NMR facility for this purpose.

You might have encountered some difficulties with Autolock on the I400 and I500 due to a Lockphase change after the last week’s power outage. This problem has been fixed.
