60 vs. 90MHz Sample: 2M Ibuprofen in CDCl3
The stack plot above is a comparison of ibuprofen recorded at both 60 and 90MHz. Better signal to noise, better resolution and fewer 2nd order effects are apparent in the 90MHz spectrum.
The single scan 1H spectrum of ibuprofen is show below at 60 and 90MHz with the assignments.
Comparison of 60 (upper) and 90MHz (lower) spectra for ibuprofen. Sample was 2M concentration (200mg in 0.5mL CDCl3) and a single scan.
