1.	Under ideal conditions, a commercial X-band spectrometer can detect of the order of which of the following number of spins at room temperature?(a) 10^1(b) 10^5(c) 10^10(d) 10^12I got this question in class test.My doubt is from Electron Spin Resonance topic in section Electron Spin Resonance Spectrometers of Analytical Instrumentation
Answer» The CORRECT option is (d) 10^12 Easiest explanation: Under IDEAL conditions, a X-band spectrometer is capable of detecting of the ORDER of 10^12 SPINS at ROOM temperature. ESR is very sensitive.
