Raman spectroscopy analyzer

Raman Spectroscopy Analyzer

Purpose

The Raman Spectroscopy Analyzer skill provides molecular-level characterization of nanomaterials through vibrational spectroscopy, enabling structural identification, defect analysis, and chemical mapping.

Capabilities

• Raman spectrum acquisition and processing
• Peak identification and assignment
• SERS (Surface-Enhanced Raman) analysis
• Raman mapping and imaging
• Resonance Raman analysis
• Graphene/CNT characterization (D/G ratio)

Usage Guidelines

Raman Analysis

1. Spectrum Acquisition

   • Select appropriate excitation wavelength
   • Optimize power to avoid damage
   • Apply baseline correction

2. Peak Analysis

   • Identify characteristic peaks
   • Calculate peak ratios (D/G for carbon)
   • Assess crystallinity

3. Mapping

   • Generate chemical maps
   • Identify phase distributions
   • Quantify heterogeneity

Process Integration

• Multi-Modal Nanomaterial Characterization Pipeline
• In-Situ Characterization Experiment Design
• Structure-Property Correlation Analysis
