Dokazi FTIR ne podpirajo trdne identifikacije kot N-(Phenylmethyl)acetamide, čeprav je to najbližji vnos v knjižnici. Opazovani spekter je bolje opisati široko kot organski material, ki vsebuje karbonil, z močnim alifatskim značajem in esterom podobnim vzorcem C=O/C-O. Ta širša smer je kemično bolj podprta kot specifična amidna ali dušikova dodelitev.
Priporočeni naslednji koraki: Re-examine the full spectrum for a weak or broad N-H/O-H stretching region between about 3200 and 3600 cm-1 to test amide or alcohol involvement. Inspect the 1600-1500 cm-1 region for aromatic ring bands; their presence or absence would help distinguish benzyl/aromatic compounds from aliphatic esters. Check for the characteristic ester pair by confirming a strong C=O near 1735 cm-1 together with intense C-O bands across roughly 1300-1000 cm-1. If available, run GC-MS or LC-MS to determine whether the sample is a long-chain ester, another oxygenated aliphatic compound, or a mixture.
