Magnetless resonance spectrometer is up and running
After a long break the Tecmag Redstone spectrometer (NQR and NMR spectra of magnetically ordered materials in zero external magnetic field) became operational again. People started to pass their first samples to the Center. The figures show the NMR signal of bulk 57Fe nuclei and samples of the Fe100-xVx type and others.

New probehead
As a result of self-sacrificing actions of our eminent staff a new 500 MHz low-temperature inverse two-channel 1H/13C NMR probehead which is capable to measure UV absorption and NMR spectra simultaneously appeared in our Center.

First 3D NMR spectrum
The first HNCO 3D NMR spectrum of uniformly 13C and 15N labeled ubiquitin was recorded in our Center for a new Biomolecular NMR Laboratory working under the leadership of N. R. Skrynnikov. The Laboratory stuff particularly thank our specialist M. A. Vovk.
