A Comprehensive Set of Distance Rulers for Pulsed Dipolar ESR Spectroscopy
Why Do We Need Rulers

Standard for Calibration of Pulsed Dipolar ESR Spectrometer

Benchmarking of Data Processing Criteria
Criteria for Rulers

Feature
- Known Structure of Molecules
- Rigid in Nature
- Stable for Years
- Biologically Revelant
Other Rulers vs ACERT Rulers
Why we are better
Other Rulers
- Limited Distance Range
- Only Unimodal Distances
- Applicable at Low Temperature
ACERT Rulers
- Comprehensive Range of Distances
- Possess Bimodal Distribution
- Applicable at both Low and Room Temperature
Unimodal Rulers
The distance ranges from 1.5 nm to 3.9 nm, covering complete range of practical distributions in Pulsed Dipolar ESR Spectroscopy
