自己沒做過EPR實(shí)驗(yàn),對這方面的知識了解也甚少,老板給的兩個(gè)樣品去外校測試了,數(shù)據(jù)什么都有了,但是有些不懂,希望高手幫幫忙處理一下,共六個(gè)數(shù)據(jù),謝謝!下面是數(shù)據(jù)處理說明,數(shù)據(jù)已經(jīng)上傳到納米盤了,急用,謝謝!(我們一般實(shí)驗(yàn)數(shù)據(jù)一般都是用Origin處理的) 文檔數(shù)據(jù)txt文件只有Y軸ESR掃場信號數(shù)據(jù)(僅取數(shù)據(jù)欄中的前8192個(gè)點(diǎn),第8193點(diǎn)及后面的數(shù)據(jù)為譜儀程序雙共振腔中的Channel 2數(shù)據(jù),不需要),X軸數(shù)據(jù)請自己按實(shí)驗(yàn)條件添加,公式為:H0 + (i-1)* SW/8191,(其中H0為初始場,SW指的是磁場掃寬Scan Width),Origin有這方面的添加功能(打開Origin,鼠標(biāo)點(diǎn)X軸按右鍵在Set Column Values上,會(huì)出現(xiàn)小方框,把上述公式輸入即可,注意X軸的值在設(shè)置上為:From Row 1 to 8192,)。 請按傳給您的txt文件數(shù)據(jù),把其它的相關(guān)數(shù)據(jù)在Origin上做出來即可。 有關(guān)g值標(biāo)定,按下述公式計(jì)算: g = 0.07145×(MHz)/H(mT) 其中:-微波頻率(單位:MHz),H磁場(單位:mT),在txt文件里都有這方面對應(yīng)的數(shù)據(jù)。 http://d.namipan.com/d/bc551d3c2 ... 6fda9a248d4e69a0200 |

你好 對于X軸如何算不清楚 想請教一下。H0 + (i-1)* SW/8191中的H0 和SW是下列數(shù)據(jù)中的哪兩個(gè)? ===== Data Head =================================== file name = a-323K data number = 1 data length = 8192 data sort = complex x-range min = 225.575 x-range = 200 x unit = mT min value = 0 max value = 0 y unit = ~ x-view min = 225.575 x-view max = 425.575 y-view min = -2048 y-view max = 2047 type = cAcqu ===== General Parameter ========================== title = ~ sample name = ~ comment = ~ system name = ~ version = ~ date = 2010/07/01~15:50 origin file = current.tmp prev. file = 4-1 ===== Spectrometer Parmeters ===================== type = tyFA200 center field = cf325.575 sweep control = SWend sweep time = st60.00 sweep width(fine) = sw1 sweep width(coar) = sw+2 modulation freq. = fq100.00 receiver mode = rmfirst phase = ph000.0 phase (fine) = pH0 mod. width(fine) = md0.25 mod. width(coarse)= md+0 amplitude(fine) = am1.00 amplitude(coarse) = am-1 time constant = tc0.1 zero = zr32768 micro frequency = uF9052.767 micro freq. unit = UFMHz micro power = uP0.998000 micro power unit = UPmW micro phase = uH470 micro coupling = uC315 micro 30db = 30off micro ref = REon micro gunp = GUon receiver mode2 = rmsecond phase2 (fine) = pH0 amplitude2(fine) = am2.000 amplitude2(coars) = am+0 time constant2 = tc0.03 zero2 = zr32768 vt type = RESRVD temp. control = RESRVD temperature = RESRVD temperature unit = RESRVD reserved area = RESRVD ===== Aqcuisition Parameters ===================== accumulation count = 1 delay time = 0 interval time = 0 reserved(int) = 0 sampling time = 60 reserved(float) = 0 accumulation mode = normal baseline = AD sampling mode = sweep signal triger = RSRVED reference file name = RSRVED reserved(char) = RSRVED ===== Esr Data =================================== length = 8192 |
