Tick one box per statement. Red: need help. Amber: partly confident. Green: can do independently.

I canRedAmberGreen
Molecular ions, fragments and accurate mass
interpret molecular, base, fragment and isotope signals with conservation checks
calculate and evaluate accurate masses for candidate formulae
Infrared evidence and functional groups
interpret IR axes, absorption positions and group evidence with appropriate limits
use fingerprint comparisons and reaction spectra without overclaiming identity or yield
Carbon-13 NMR environments
predict and justify carbon environments and chemical shifts using symmetry and reference data
evaluate carbon-spectrum signal counts, decoupling and intensity limitations
Proton NMR shifts, integration and splitting
predict proton environments, integration and simple first-order splitting patterns
interpret exchangeable signals and D2O evidence with conditions
deduce and test whole structures using shifts, areas, splitting and complementary evidence
Thin-layer chromatography and Rf
perform, calculate and evaluate TLC using appropriate phases and references
evaluate chromatographic identity and purity claims
Column methods, coupled analysis and evidence
select GC or HPLC and interpret retention and quantitative signals with calibration
evaluate coupled chromatography–mass evidence and design a combined unknown workflow
