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.
