Key Points

Utilizing dual frequency comb spectroscopy enabled precise measurements of ethanol in the infrared spectral range.
The system achieved a spectral resolution of 8 MHz, enhancing the ability to analyze gas mixtures accurately.
Measurements were conducted across the 800–1350 cm-1 range under controlled pressure conditions.
The frequency scale was anchored to a rubidium atomic clock, ensuring stability and precision in measurements.

Implication

Measurements of gaseous ethanol at 1 mbar pressure exhibit 8-MHz resolution, suggesting precise spectral analysis.

Abstract

Using electro-optically sampled dual-comb spectroscopy we performed measurements of gaseous ethanol at 1mbar pressure across 800–1350cm -1 (7.4–12.5µm) spectral range with 8-MHz spectral resolution and frequency scale referenced to a rubidium atomic clock.
