The W. M. Keck Solid State Nuclear Magnetic Resonance Spectrometer Laboratory consists of a three channel multi-nuclear instrument built around a 7 Telsa superconducting solenoid magnet.  Accessible frequency range spans 30 MHz (15N-lowest) to 300 MHz (1H-highest).  The GL SS-NMR has two 1 KW AMT Solid State Broad Band amplifiers and a narrow band (Chemagnetics/Varian) Amplifier (1.5 KW) for 1H and 19F- SS-NMR. The NMR has five Magic Angle Spinning Probes including 3 double resonance probes (H-X): 7.5 mm (OD) with 7000 Hz Max MAS, 5 mm (OD) with 12,000 Hz Max MAS, 2.5 mm (OD) 30,000 Hz Max MAS; one triple resonance probe (H-X-Y) with 4.0 mm (OD) and 16,000 Hz Max MAS; and one single resonance (1H or 19F) CRAMPS probe, 5mm (OD) 5,000 Hz Max MAS.  Nuclei studied at GL include 1H, 2H, 11B, 13C, 15N, 17O, 19F, 23Na, 27Al, 29Si, 31P.  There are many other nuclei we could study in the 30-300 MHz range at 7 Tesla using the GL SS-NMR facility.  This facility was supported by the W. M. Keck Foundation, the National Science Foundation (MRI), and Carnegie Insitution.
