Click For Summary
Omega 1, or ω1, in NMR experiments represents the nutation frequency, which is defined by the equation ω1 = -γB1, where γ is the gyromagnetic ratio and B1 is the radio frequency field. It indicates the frequency at which the magnetization vector precesses around the magnetic field in a rotating coordinate system. This frequency is crucial for achieving resonance conditions during NMR experiments, allowing for effective manipulation of nuclear spins. Understanding ω1 helps in optimizing pulse sequences and improving signal detection in NMR spectroscopy. Overall, ω1 is essential for interpreting and executing NMR techniques accurately.

Hello,

The nutation frequency in NMR is given as

\omega_{1} = - \gamma B_{1}
Here gamma is the gyromagnetic ratio and B1 the radio frequency field.

My problem is that this is all well and good, but what does omega 1 actually represent in an NMR experiment? What is its physical meaning?

Regards,

Peter

Thread 'Unexpected irregular reflection signal from a high-finesse cavity'

I am observing an irregular, aperiodic noise pattern in the reflection signal of a high-finesse optical cavity (finesse ≈ 20,000). The cavity is normally operated using a standard Pound–Drever–Hall (PDH) locking configuration, where an EOM provides phase modulation. The signals shown in the attached figures were recorded with the modulation turned off. Under these conditions, when scanning the laser frequency across a cavity resonance, I expected to observe a simple reflection dip. Instead...
