# FTIR Analyzer

## Purpose

The FTIR Analyzer skill provides molecular characterization of nanomaterials through infrared spectroscopy, enabling identification of functional groups, surface modifications, and chemical bonding.

## Capabilities

- ATR-FTIR for nanoparticle surfaces
- Functional group identification
- Surface modification verification
- Gas-phase FTIR for reactions
- Diffuse reflectance (DRIFTS)
- Spectral library searching

## Usage Guidelines

### FTIR Analysis

1. **Sample Preparation**
   - Use ATR for nanoparticles
   - Ensure good contact for ATR
   - Consider KBr pellet for transmission

2. **Spectrum Analysis**
   - Identify characteristic bands
   - Compare to reference spectra
   - Quantify using Beer-Lambert

3. **Surface Chemistry**
   - Monitor ligand exchange
   - Verify functionalization
   - Detect degradation products

## Process Integration

- Multi-Modal Nanomaterial Characterization Pipeline
- Nanomaterial Surface Functionalization Pipeline
