Bruker Pulse Sequences for 2D Heteronuclear Shift Correlation

• Bruker DMX 15N-1H 2D HSQC with Sensitivity-enhanced
• Bruker AMX 15N-1H 2D HSQC with Sensitivity-enhanced
• HMBC with gradient selection of echo and antiecho in t1 for suppression of t1-noise.
• hsqc employing gradients for coherence selection. Phase sensitive by sampling +/- coherence in alternate scans.
• selective hmbc with gradients; used when the selective 180 is greater than approx 1.5 ms
• selective hmbc with gradients; used when the selective 180 is less than approx 1.5 ms
• hsqc with selective 180(1H) pulses for high S/N
