Relaxation time under spin locking T_1ρ as a function of the correlation time, τ_c: solid blue - ${\omega }_1=2\pi \times 2000\frac{1}{s}$, dashed red - ${\omega }_1=2\pi \times 500\frac{1}{s}$. V=5400 nm³, $n=33\frac{\mathit{\text{molecules}}}{n{m}^3}$, and F = 2π. The inset shows the minimum of the T_1ρ at ${\omega }_1=2\pi \times 500\frac{1}{s}$.
