Absorption of RF Energy or NMR RF Pulse
{"Image DocumentName": "Absorption of RF Energy or NMR RF Pulse", "Image ImageDescription": "B1 off\u2026 (or off-resonance) Mo. z. x. B1. Mxy. y. w1. Classic View: - Apply a radio-frequency (RF) pulse a long the y-axis. - RF pulse viewed as a second. field (B1), that the net. magnetization (Mo) will. precess about with an. angular velocity of w1. -- precession stops when B1. turned off. Quantum Description: - enough RF energy has been. absorbed, such that the. population in a/b are now. equal. - No net magnetization along. the z-axis. 90o pulse. w1 = gB1. DE = h n. a. b. Bo > 0. Please Note: A whole variety of pulse widths are possible, not quantized dealing with bulk magnetization.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
