• Efsta bókasafnssamsvörun: 2-Bromoheptane #232

• The leading library candidate 2-Bromoheptane is not strongly supported because the reported similarity is 0.000.
• The top library candidates do not converge on one chemical class, which limits confidence in any narrow identification.
• Features near 1645 and 3170-3178 cm⁻¹ are not well explained by a simple saturated bromoalkane alone.
• The low-wavenumber bands are not sufficient to confirm bromine substitution versus other fingerprint-region causes.
• The current evidence cannot distinguish reliably between a simple alkane, a halogenated alkane, or a mixture containing an aliphatic hydrocarbon component.
• Because no literature-backed reference match was recovered, the material direction must remain broad.

Mælt með næstu skrefum: Verify halogen content with complementary elemental analysis such as XRF, EDS, or combustion/ion chromatography if bromine or chlorine is specifically suspected. Collect a higher-quality FTIR spectrum with good baseline control and sample preparation focused on the fingerprint region below 800 cm⁻¹, where halogen-related bands would be most informative. Use GC-MS if the sample is volatile or solvent-extractable, since a small halogenated alkane such as 2-Bromoheptane would be much more securely tested by mass spectrometry than by this FTIR match alone. If the sample may be a mixture, separate volatile and nonvolatile fractions before re-running FTIR or GC-MS.
