🔬 13C-HSQC Data Processing Tool
13C Spectrum (Chemical Shifts)
Supports comma, Tab, or space separation. Enter chemical shifts only.
HSQC Data (F1-¹³C, F2-¹H[, Intensity])
Supports comma or Tab separation. Phase-sensitive mode auto-detected by 3rd intensity column.
Shift Tolerance (ppm):
Mode: Auto-detect
▶ Process Data
Matched Results (¹³C aligned with ¹H)
Flag meanings (phase-sensitive mode):
• 0 = Quaternary C (no HSQC correlation)
• 1 = CH or CH₃ (positive intensity, single ¹H)
• 2 = CH₂ (negative intensity, ¹H values merged with "|")
Unmatched HSQC Peaks (for verification)
Peaks not matched to any ¹³C signal. Useful for manual review.
