Abstract:
1. A probe for NMR measurement comprising: a measuring Radio Frequency (RF) coil for measuring a nuclear magnetic resonance (NMR) that sends a high frequency signal at a predetermined resonant frequency to a sample placed in an evenly distributed magnetic field and, at the same time, receives a free induction decay (FID) signal emitted from the sample in response to the high frequency signal that has been sent; a signal line through which the high frequency signal and the FID signal are sent to said measuring RF coil; a stage that holds said measuring RF coil; and a probe container that holds said stage, wherein said measuring RF coil comprises turns and lead lines, said turns comprising a conductive line provided from one end to another end in such a way that the line surrounds a sample tube in which the sample is stored, said lead lines being extended from both ends of said turns, a first capacitor (C a second capacitor (C a third capacitor (C a fourth capacitor (C another end of each of said first, second, third, and fourth capacitors is grounded, said first lead line and said second line are connected via a fifth capacitor (C said third lead line and said fourth line are connected via a sixth capacitor (C a fifth lead line, which is connected between a lead-out point on said turn of said second lead line and a lead-out point on said turn of said third lead line, is connected to said signal line.
