“…Ravat et al, 2007, Bonde et al, 2014, this is still a point of confusion: some publications seem to have wrong corrections because their equations and wavenumber units are not consistent between them (e.g. Dolmaz et al, 2005a;Qingqing et al, 2008;Bilim et al, 2011;Hisarli et al, 2011, Githiri et al, 2012Saleh et al, 2012;Hsieh et al, 2014;Afshar et al, 2016;Mousa et al, 2017;Aydemir et al, 2018;Quintero et al, 2019), some others use a wrong unit system (e.g. Azab, 2014;Usman et al, 2018).…”
