<span style='font-family:Arial'> <center><h3>STARTMAS: a MAS-based Method for Acquiring Isotropic NMR Spectra of Spin I = 3/2 Nuclei in Real Time </h3><p> <table> <tr><td valign=top> <p align="justify"> <b>Abstract</b><br> We describe a novel method, which we call STARTMAS, that allows acquisition of high-resolution or "isotropic" spin I = 3/2 NMR spectra in solids in real time. Unlike the DOR technique of Samoson et al. [Mol. Phys. 65, 1013 (1988)], STARTMAS is performed on a standard MAS probe and fast spinning rates are possible. The method consists of a multiple-pulse sequence interleaved with real-time data acquisition and exploits satellite and double-quantum transitions. We show that STARTMAS experiments can be used to obtain one-dimensional DOR-like spectra or provide an "ultrafast" route to high-resolution two-dimensional spectra.</td>
