SUMMARY

This discussion focuses on converting Mossbauer spectroscopy data from channel counts to velocity counts for a ferrite sample. The user seeks guidance on using MOSSWIN and IGOR PRO software for this conversion but faces challenges. Key factors for successful conversion include the type of source motion (sinusoidal or triangular), measurement velocity, and the number of data points or channels. Understanding the reference sample is crucial for accurate conversion, particularly when aligning with alpha iron foil.

PREREQUISITES
  • Mossbauer spectroscopy fundamentals
  • Understanding of data formats in MOSSWIN and IGOR PRO
  • Knowledge of source motion types (sinusoidal and triangular)
  • Familiarity with velocity measurement techniques
NEXT STEPS
  • Research how to use MOSSWIN for Mossbauer data analysis
  • Learn about IGOR PRO data manipulation techniques
  • Study the principles of converting channel data to velocity scale
  • Explore the significance of reference samples in Mossbauer spectroscopy
USEFUL FOR

Researchers and scientists working with Mossbauer spectroscopy, particularly those analyzing ferrite samples and needing to convert data formats for accurate interpretation.

i have a mossbauer data for a ferrite sample in terms of channel vs counts, i need to convert it into velocity vs counts. i don't have any software, i tried to download the demo versions of MOSSWIN and IGOR PRO but i am unable to know how to convert them. Please guide me for the conversion.

Is your raw spectrum is folded (not convolution)?..
if it is folded...you can easily convert..if not i can help..
If you want to convert please tell me the following:
1. What is source motion (sinusoidal or triangular)?..
2. measurement velocity ?
3. no. of data point or channels?
For converting the raw spectrum to a velocity scale spectrum w.r.t. source no need to know the iron spectrum's zero velocity channel..
But converting the spectrum relative to alpha iron foil one needs to know it...
Or else with which reference sample you want to convert..?
good luck.
