NMR for CH3OC(CH2OCH3)3
Construct a simulated 1H NMR spectrum, Including proton Integrations, for CH3OC(CH2OCH3)3 (see Hint). Drag the appropriate splitting patterns to the approximate chemical shift positions; place the integration values in the small bins above the associated chemical shift. Splitting patterns and integrations may be used more than once, or not at all, as needed. Likewise, some bins might remain blank. Note that peak heights are arbitrary and do not indicate proton integrations.
