Raman Fitting

Overview

This skill guides the analysis and curve fitting of Raman spectroscopy data, particularly for materials like graphene where characteristic peaks (G, D, 2D bands) must be accurately extracted. The primary challenge in these tasks is ensuring correct data ingestion before any analysis begins.

Critical First Step: Data Parsing Verification

Before any fitting or analysis, verify data is parsed correctly. This is the most common source of failure in spectroscopic data analysis.

Data File Inspection Protocol

1. Read raw file content first - Examine the first 5-10 lines of the raw data file to understand the actual format
2. Identify potential format issues:
   • Line number prefixes (e.g., "1→", "2→" before actual data)
   • Decimal separators (comma vs period - European vs US format)
   • Column delimiters (tab, comma, semicolon, whitespace)
   • Header lines that need to be skipped
   • Encoding issues (UTF-8, ISO-8859-1, etc.)
